The performance of a computer or other electronic systems has typically been constrained by the speed of its slowest active elements. Until recently, those elements were the microprocessor and the memory components that controlled the overall system's specific functions and calculations. However, with the advent of new generations of microprocessors, memory components and their data, there is intense pressure to provide the user increased processing power and speed at a decreasing unit cost. As a result, the engineering challenge of conditioning the energy delivered to electrical devices has become both financially and technologically difficult. Since 1980, the typical operating frequency of the mainstream microprocessors has increased approximately 240 times, from 5 MHz (million cycles per second) to approximately to 1200 MHz+ by the end of the year 2000. Processor speed is now matched by the development and deployment of ultra-fast RAM architectures. These breakthroughs have allowed boosting of overall system speeds past the 1 GHz mark. During this same period, passive componentry technologies have failed to keep up and have produced only incremental changes in composition and performance. Advances in passive component design changes have focused on component size reduction, slight modifications of discrete component electrode layering, new dielectric discoveries, and modifications of manufacturing production techniques that decrease component production cycle times.
Not to be overlooked, however, is the existence of a major limitation in the line conditioning ability of a single passive component and for many passive component networks. This limitation presents an obstacle for technological progression and growth in the computer industry and remains as one of the last remaining challenges of the +GHz speed system. This constraint to high-speed system performance is centered upon the limitations created by the supporting passive componentry that delivers and conditions energy and data signals to the processors, memory technologies, and those systems located outside of a particular electronic system.
Additionally, at these higher frequencies, energy pathways are normally grouped or paired as an electrically complementary element or elements that electrically and magnetically must work together in harmony and balance. An obstacle to this balance is the fact that two discrete capacitors manufactured in the same production batch can easily posses a variability in capacitance, ranging anywhere from 15%-25%. While it is possible to obtain individual variations of capacitance between discrete units of less than 10%, a substantial premium must be paid to recover the costs for testing, hand sorting manufactured lots, as well as the additional costs for the more specialized dielectrics and manufacturing techniques that are needed to produce these devices with reduced individual variance differences required for differential signaling. Therefore, in light of the foregoing deficiencies in the prior art, the applicant's invention is herein presented.
It is another object of the invention to provide line-to-line and line-to-ground capacitive or inductive coupling between internal plates and/or conductive electrodes that create a state of effective differential and common mode electromagnetic interference filtering and/or surge protection. Additionally, a circuit arrangement utilizing the invention will comprise of at least one line conditioning circuit component constructed as a plate. Electrode patterns are provided on one surface of the plate and the electrode surfaces are then electrically coupled to electrical conductors of the circuit. The electrode patterns, dielectric material employed and common conductive plates produce commonality between electrodes for the electrical conductors producing a balanced (equal but opposite) circuit arrangement with an electrical component coupled line-to-line between the electrical conductors and line-to-ground from the individual electrical conductors. The particular electrical effects of the multi-functional energy conditioner are determined by the choice of material between the electrode plates and the use of ground shields which effectively house the electrode plates within one or more created Faraday like shield cages. If one specific dielectric material is chosen, the resulting multi-functional energy conditioner will be primarily a capacitive arrangement. The dielectric material in conjunction with the electrode plates and common conductive plates will combine to create a line-to-line capacitor that is approximately � the value of the capacitance of the two line-to-ground capacitors make up an attached and energized invention. If a metal oxide varistor (MOV) material is used, then the multi-functional energy conditioner will be a capacitive multi-functional energy conditioner with over current and surge protection characteristics provided by the MOV-type material. The common conductive plates and electrode plates will once again form line-to-line and line-to-ground capacitive plates, providing differential and common mode filtering accept in the case of high transient voltage conditions. During these conditions, the MOV-type varistor material, which is essentially a nonlinear resistor used to suppress high voltage transients, will take effect to limit the voltage that may appear between the electrical conductors.
In a further embodiment, a ferrite material may be used adding additional inherent inductance to the multi-functional energy conditioner arrangement. As before, the common ground conductive and electrode plates form line-to-line and line-to-ground capacitive plates with the ferrite material adding inductance to the arrangement. Use of the ferrite material also provides transient voltage protection in that it to will become conductive at a certain voltage threshold allowing the excess transient voltage to be shunted to the common conductive plates, effectively limiting the voltage across the electrical conductors. Numerous other arrangements and configurations are also disclosed which implement and build on the above objects and advantages of the invention to demonstrate the versatility and wide spread application of multi-functional energy conditioners within the scope of the present invention.
Higher operating frequencies of circuitry for the most part, require the user to develop combinations of single or multiple passive elements such as inductors, capacitors, or resistors to create L-C-R, L-C, and R-C discrete component networks used to control energy delivered to a system load. However, prior art, discrete, L-CR, L-C, R-C component networks at frequencies above 200 MhZ begin to take on characteristics of transmission lines, or can even exhibit microwave-like features at still higher frequencies. This can allow unsuppressed or undiminished parasitics, or the connection structures that combine externally between all of the discrete elements into said network, to degrade, slow down or otherwise contribute noticeable degradation of the energy propagating along the circuit over a wide range of frequency operations. This can be substantially harmful to the larger circuit said network is attached into. Rather than providing a lump capacitance, resistance or inductance that such a network was designed for, at higher frequencies, capacitive parasitics that are attributed to the internal electrodes located inside prior art component networks can be one of many reasons or sources of energy degradation, debilitation or sub-specified performance to the circuit. Said sub-par performance losses such as, but not limited to, data drop, line delays, etc. and can contribute to a measurable circuit in-efficiency.
Common mode and differential mode energies differ in that they propagate in different circuit paths. Common mode noise will can be caused electrostatic induction which results from un-equal capacitance between conductive pathways and the surroundings. Noise voltage developed, will be the same on both wires and/or, it can be caused by electromagnetic induction magnetic fields from a conductive pathway linking paired or multiple conductive pathways un-equally with any noise voltage developed, essentially, the same; on both paired, conductive pathways. Noise energy will travel on the outer skin surface of conductors. Differential noise, is normally created by voltage imbalance within an energized circuit, Interference that causes the potential of one side of the signal transmission path to be change relative to the other side.
Still referring to FIG. 1, the physical relationship of common conductive plates 14, electrode plates 16A and 16B, electrical conductors 12 a and 12 b and material 28 will now be described in more detail. The starting point is center common ground conductive plate 14. Center plate 14 has the pair of electrical conductors 12 a and 12 b disposed through their respective insulating apertures 18 which maintain electrical isolation between common ground conductive plate 14 and both electrical conductors 12 a and 12 b. On either side, both above and below, of center common ground conductive plate 14 are electrode plates 16A and 16B each having the pair of electrical conductors 12 a and 12 b disposed there through. Unlike center common ground conductive plate 14, only one electrical conductor, 12 a or 12 b, is isolated from each electrode plate, 16A or 16B, by an insulating aperture 18. One of the pair of electrical conductors, 12 a or 12 b, is electrically coupled to the associated electrode plate 16A or 16B respectively through coupling aperture 20. Coupling aperture 20 interfaces with one of the pair of electrical conductors 12 through a standard connection such as a solder weld, a resistive fit or any other method which will provide a solid and secure electrical connection. For multi-functional energy conditioner 10 to function properly, upper electrode plate 16A must be electrically coupled to the opposite electrical conductor 12 a than that to which lower electrode plate 16B is electrically coupled, that being electrical conductor 12 b. Multi-functional energy conditioner 10 optionally comprises a plurality of outer common conductive plates 14. These outer common conductive plates 14 provide a significantly larger conductive ground plane and/or image plane when the plurality of common conductive plates 14 are electrically connected to an outer edge conductive band, conductive termination material or attached directly by tension seating means or commonly used solder-like materials to an larger external conductive surface (not shown) that are physically separate of the differentially conductive plates 16 a and 16 b and/or any plurality of electrical conductors such as 12 a and 12 b for example. Connection of common conductive plates 14 to an external conductive area helps with attenuation of radiated electromagnetic emissions and provides a greater surface area in which to dissipate over voltages and surges.
Principals of a Faraday cage-like structure are used when the common plates are joined to one another as described above and the grouping of common conductive plates together co-act with the larger external conductive area or surface to suppress radiated electromagnetic emissions and provide a greater conductive surface area in which to dissipate over voltages and surges and initiate Faraday cage-like electrostatic suppression of parasitics and other transients, simultaneously. This is particularly true when plurality of common conductive plates 14 are electrically coupled to earth ground (not shown) but are relied upon to provide an inherent ground for a circuit in which the invention is placed into an energized with. As mentioned earlier, inserted and maintained between common conductive plates 14 and both electrode plates 16A and 16B is material 28 which can be one or more of a plurality of materials having different electrical characteristics.
The larger external conductive area 34 will be described in more detail later but for the time being it may be more intuitive to assume that it is equivalent to earth or circuit ground. The larger external conductive area 34, can be coupled with the center and the additional common conductive plates 14 to join with the central plate 14 to form, one or more of common conductive plates 14 that are conductively joined and can be coupled to circuit or earth ground by common means of the art such as a soldering or mounting screws inserted through fastening apertures 22 which are then coupled to an enclosure or grounded chassis (not shown) of an electrical device. While multi-functional energy conditioner 10 works equally well with inherent ground 34B coupled to earth or circuit ground 34, one advantage of multi-functional energy conditioner 10's physical architecture is that depending upon energy condition that is needed, a physical grounding connection can be unnecessary in some specific applications.
A conductive termination material 112D is also applied to the sides of plates 112 during manufacturing so that termination material 112D allows a conductive connection of at least the perimeter of invention 110s' plurality of common conductive plate electrodes 112A, 112B, 112C to be joined conductively together to form a single conductive structure capable of sharing a same conductive pathway to an external conductive area 34 or surface (not shown) when placed into a circuit and energized. The pairs of incoming electrical conductors each have a corresponding electrode pair within multi-functional energy conditioner 110. Although not shown, the electrical conductors pass through the common conductive plates 112 and the respective conductive electrodes. Connections are either made or not made through the selection of coupling apertures 120 and insulating apertures 114. The common conductive plates 112 in cooperation with conductive electrodes 118 a thru 118 h perform essentially the same function as electrode plates 16A and 16B of FIGS. 1 and 1A.
FIG. 5B shows a schematic representation of differential and common mode multi-conductor multi-functional energy conditioner 110 having four differential and common mode filter pin pair arrangements. The horizontal line extending through each pair of electrodes represents the common conductive plate electrodes 112A, 112B and 112C with the lines encircling the pairs being the conductive isolation material 112 a. The conductive isolation material 112 a is electrically coupled to common conductive plate electrodes 112A, 112B and 112C and side conductive termination material 112D to provide a conductive grid that is further separated from electrode plates 118 a through 118 h by areas left free of conductive material that allows a separation of each of the conductive electrode plates 118 a through 118 h from one another and the conductive grid, as well. The corresponding conductive electrodes 118 a thru 118 h positioned on support material plates 116A and 116B, both above and below the center common ground conductive plate 112, and form line-to-ground common mode decoupling capacitors. Each conductive plate electrodes 118 a thru 118 h common conductive plate electrodes 112A, 112B and 112C and support material plates 116A and 116B, are separated from the others by dielectric material 122. When multi-functional energy conditioner 110 is connected to paired, electrical conductors via coupling apertures 120 such as those found in electrode plates 118 a and 118 c, multi-functional energy conditioner 110 forms a common mode and differential mode filter.
One trend found throughout modern electronic devices is the continuous miniaturization of equipment and the electronic components that make up that equipment. Capacitors, the key component in multi-functional energy conditioner arrangements, have been no exception and their size has continually decreased to the point where they may be formed in silicon and imbedded within integrated circuits only seen with the use of a microscope. One miniaturized capacitor which has become quite prevalent is the chip capacitor which is significantly smaller than standard through hole or leaded capacitors. Chip capacitors employ surface mount technology to physically and electrically connect to electrical conductors and traces found on circuit boards. The versatility of the architecture of the multi-functional energy conditioner of the present invention extends to surface mount technology as shown in FIG. 6. Surface mount multi-functional energy conditioner 400 is shown in FIG. 6A with its internal construction shown in FIG. 6B. Referring to FIG. 6B, common conductive support plate 412 is sandwiched between first differential support plate 410 and second support differential plate 414. Common conductive support plate 412 and first and second differential support plates 410 and 414 are each comprised of material 430 having desired electrical properties dependent upon the material chosen. As for all embodiments of the present invention, Applicant contemplates the use of a variety of materials such as but not limited to dielectric material, MOV-type material, ferrite material, film such as Mylar and newer exotic substances such as sintered polycrystalline.
With respect to the common conductive electrode 424 and the range of the over lap with respect to the equally sized differential plates 416 and 426 can be essentially inset to a degree that when energized the entrapment of parasitics attempting to escape or enter the area occupied by differential electrodes 416 and 426 is sufficient to prevent such degradation from occurring. Insetting of differential conductive plates 416 and 426 to a point with respect to a larger set of common plates 424, 424a, 424b that are sandwiching differential plates 416 and 426 and will increase the electrostatic shielding effectiveness during an energized state. This orientation allows an electrical conductor to be coupled electrically to either individual differential plate 416 and 426 but not necessarily both, so to allow for differentially phased, but complementary energy conditioning, between paired, but oppositely positioned, differential conductors, 416 and 426.
FIGS. 8 through 9 are directed towards embodiments of the multi-functional energy conditioner configured for use with electric motors but certainly not limited by this embodiment from performing energy conditioning in other electronics applications. Electric motors are a tremendous source of electromagnetic emissions and unbalance. This fact is evident even to layman, as most people have experienced running a vacuum cleaner in front of an operating television set and noticing �snow� fill the screen. This interference with the television is due to the electromagnetic emissions from the motor. Electric motors are used extensively in a number of home appliances such as washing machines, dryers, dishwashers, blenders, and hair dryers. In addition, most automobiles contain a number of electric motors to control the windshield wipers, electric windows, electric adjustable mirrors, retractable antennas and a whole host of other functions and can number from 25 motors per automobile to over 150 per luxury automobile. Due to the prevalence of electric motors and increased electromagnetic emissions standards, there is a need for differential and common mode filtering ability in one integrated packaged that can reduce and in many cases eliminated all but one passive component to provide the needed filtering and noise suppression without use of inductor or ferrite components used in addition to an invention embodiment.
Electric motor filter 180 may be made in any number of shapes but in the preferred embodiment shown in FIG. 8, it appears as a rectangular block comprised of material 182 having one of a number of predetermined electrical properties. FIG. 8a shows the outer construction of filter 180, which consists of a rectangular block of material 182 having an insulated shaft aperture 188, disposed through filter 180's center. The 188 aperture is not necessarily common to this particular usage and is considered more as a convenience to the user than any electrical conditioning enhancements attributed to any said 188 aperture and thus it can be eliminated and optimally placement space is designed in for use. Conductive bands 184 and 194 and common conductive bands 186. FIG. 8b shows a side view of filter 180 with the arrangement of conductive bands 184 and 194 and common conductive band 186 being electrically and physically isolated from one another by sections of material 182 positioned between the various bands. FIG. 8c shows a cross section along an imaginary centerline of FIG. 8a. As in all previous embodiments, the physical architecture of the present invention is comprised of conductive electrodes 181 and 185 with common conductive electrode 183 sandwiched in between. Material 182 having predetermined electrical properties is interspersed between all of the electrodes to prevent electrical connection between the various conductive electrodes 181 and 185 and common conductive electrode 183. Similar to that of the surface mount embodiments of the present invention, filter 180 employs conductive bands 184 and 194 to electrically connect filter 180's internal electrodes to electrical conductors. Conductive electrode 181 extends fully to and comes in contact with conductive band 184 to provide the electrical interface required. As shown in FIG. 8c, conductive electrode 181 does not extend fully to come in contact with conductive band 194 which is coupled to conductive electrode 185. Although not shown, common conductive electrode 183 extends fully between common conductive bands 186 without coming in contact with conductive bands 184 and 194. Again, by coupling common conductive bands 186 to the inside of the motor case 200 (inside, not Shown) and used as a floating ground, the inherent ground provided by common conductive electrode 183 is enhanced.
FIG. 8d is a schematic representation of differential and common mode electric motor filter 180 showing conductive electrodes 181 and 185 providing the two necessary parallel plates for a line-to-line differential mode coupling capacitor while at the same time working in conjunction with common conductive electrode 183 to provide line-to-ground common mode decoupling capacitors with common conductive electrode 183 co-acting with inherent ground (not shown). Also shown are conductive bands 184, 194 and common conductive bands 186 which allow electric motor filter 180 to be connected to external differential electrical conductors and a separate conductive area (not shown), respectively. While the preferred embodiment of FIG. 8 shows three common conductive electrodes 183 and two conductive electrodes 181 and 185, Applicant contemplates the use of a plurality of common and differential electrodes to obtain, varying capacitance values through the additive effect of parallel capacitance similar to that described for previous embodiments.
FIG. 9 shows differential and common mode electric motor filter 180 electrically and physically coupled to electric motor 200. As shown in FIG. 9a, electric motor filter 180 is placed on top of electric motor 200 having motor shaft 202 extending outward there from. Motor shaft 202 is disposed through shaft aperture 188 of filter 180 with conductive bands 184 and 194 electrically coupled to connection terminals 196 which are isolated from one another and the rotor of electric motor 200. The individual connection terminals 196, although not shown, are then electrically connected to electrical supply lines providing electric motor 200 with power and return. Once electric motor filter 180 is connected/coupled to electric motor 200, motor face plate 208 is placed on top of both motor 200 and filter 180 with motor shaft 202 disposed through a similar aperture in the center of motor face plate 208. Face plate 208 is then physically coupled to the body of motor 200 through the use of clamps 206. While not shown, filter 180 may be used with its inherent ground 34 and 34B by coupling common conductive bands 186 to the motors enclosure or common conductive bands 186 may be directly wired to inside the motor shell casing.
In FIG. 10F, the filter 300 is again depicted as generally parallel electrode plates 312, 314, and 316, with electrode plates 312, 316, each sandwiched by common ground conductive plates 314 in a Faraday cage-like shield structure configuration. The current I is shown flowing in the same direction through the differential electrode plates. Note that the common ground conductive plates 314 are electrically interconnected, but insulated from the differential electrodes as has been disclosed in filter embodiments previously incorporated by reference herein.
Each of the electrodes 72, 74, 76 in FIG. 17 and each of the electrodes 72, 76 of FIG. 18, have one electrode termination portion (not numbered) extending through a generally surrounding isolation band of material 88.
The horizontal offset is approximately 0 to 20+ times the vertical distance between the electrode plate 809 and the common conductive plate 804, however, the offset distance 806 can be optimized for a particular application but all distances of overlap 806 among each respective plate is ideally approximately the same as manufacturing tolerances will allow. Minor size differences are unimportant in distance/area 806 between plates as long as the electrostatic shielding function of Faraday cage-like shield structure 800″ is not compromised. In order to connect electrode 809 to the energy pathways (not shown), the electrode 809 may have one or two portions 812 which extend 812′ beyond the edge 805 of the common conductive plates 804 and 808. These portions 812 are connected to electrode termination band 807 which enables the electrode 809 to be electrically connected to the energy pathways (not shown) by solder or the like as previously discussed. It should be noted that element 813 is a dynamic representation of the center axis point of the three-dimensional energy conditioning functions that take place within the invention and is relative with respect to the final size, shape and position of the embodiment in an energized circuit.
