A first sensor (LPS) senses LP currents. A second sensor (SPS) senses SP currents. A power module controls operating states of the SSWM based upon LPS and SPS reading(s). The LPS and/or the SPS may also sense temperatures. The power module includes a high voltage domain, isolated from a low voltage domain, that includes a gate driver coupled to the SSWM and a high voltage controller providing drive signals to the gate driver. The low voltage domain includes an LP monitor and an SP monitor that detects anomalous LP and/or SP conditions and communicates error signals to the high voltage domain and to users for reporting, diagnostic, and/or other purposes via an external communications module.

CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority to and incorporates by reference, in its entirety, U.S. Provisional Application Ser. No. 62/930,101, filed on Nov. 4, 2019, in the name of inventor Pramit Nandy, and entitled “Integrated Circuit Module for Circuit Breakers and Protected Relays.”


TECHNICAL FIELD
The technology described herein generally relates to electrical circuit breakers, relays, and contactors. More specifically, the technology described herein relates to integrated circuit modules for use in electrical circuit breakers, relays, and contactors.
BACKGROUND
Electrical circuit breakers, relays, and contactors commonly use electro-mechanical components that are configured to detect faulty and/or hazardous electrical circuit conditions and, in response thereto, cease the flow of electricity. Such electro-mechanical components, however, commonly suffer from one or more capability deficiencies such as having large footprint sizes, slow response times (as measured, for example, on a one-hundred or greater millisecond basis), varying reliability, limited if any in-rush detection capabilities, limited current sensing capabilities, limited to detection of conditions coincident with high temperatures in the component, limited phase imbalance detection capabilities, lack of remote monitoring, control and warning capabilities, limited ground fault, arc fault, hard short-circuit, over current and other detection capabilities, and otherwise. Further, such components often lack active cooling capabilities, have limited, if any, ability to perform diagnostics under line power failure scenarios, and otherwise. Accordingly, circuit breakers, relays, and contactors are needed which address these and other concerns.

DETAILED DESCRIPTION
The various embodiments described herein are directed to integrated circuit modules for electrical circuit breakers, relays, and contactors.
As shown in FIG. 1A and for at least one embodiment of the present disclosure, a system 100 for use with an alternating current power system, providing one or more phases, may include an integrated circuit breaker module “ICB” 102. As shown in FIG. 1B, and for at least one embodiment of the present disclosure, a system 150 for use with either an alternating current power system and/or a direct current power system, providing one or more phases, may include an integrated circuit relay/contactor module 152 (an “ICR”).
As used herein, an ICB 102 is commonly used for coupling an electrical circuit 137 (as commonly configured, for a non-dedicated circuit, by the wiring exiting an electrical panel and terminating at one or more outlets (not shown)) with a source 109 of electricity, such as that provided at an electrical panel in a structure. The electricity may be provided by any provider such as by a power company via a power line, by a solar panel, or otherwise. The electrical circuit 137 is commonly located within a vehicle or structure. For non-dedicated circuits, the electrical circuit 137, includes one or more standard configuration outlets into which corresponding plugs for a load 138 may be physically and electrically connected. Dedicated electrical circuits may also be used. Commonly electricity is provided at one or more phases (n), where n is an integer. Often one to three phases of electricity are provided. Such electricity may be provided at various voltages and currents, such as 120 VAC per phase at 50 to 60 Hz, and as often specified by electrical codes, regulations, and otherwise.
As further used herein, an ICR 152 is commonly used for providing a switchable connection between an electrical circuit 137 (as accessed at one or more outlets) and one or more loads 138. The ICR 152 may be configured for use with or separate of a transformer (not shown). The use of transformers and configurations thereof are well known in the art. An ICR 152 differs from an ICB 102 primarily in its intended usage thereof, with an ICR 152 being configured into a parallel circuit relationship with a load 138 and with respect to electrical circuit 137 feeding multiple loads 138, while an ICB 102 is commonly used in a series circuit relationship between an electrical source 109 and an electrical circuit 137 powering the one or more load(s) 138. That is, it is to be appreciated that the ICR 152 is configured for use in monitoring and controlling electricity provided to a particular load 138 using an existing electrical circuit 137, while the ICB 102 is directed to monitoring and controlling electricity made available by a given electrical circuit 137, such as a household electrical circuit providing 120 VAC in the United States to any of various household appliances, and at various times. Further, it is to be appreciated that ICR 152 and ICB 102 may be configured for use with circuits and loads configured for use with any desired voltages including, but not limited to, 230 VAC (as commonly used in the European Union and other countries) and/or in any desired number of circuit phases, such as three phase circuits commonly used in the United States for residential appliance applications and otherwise.
The ICB 102 may be configured to provide a switchable coupling with an electrical source 109, such as an electrical panel, electrical circuit, transformer, or the like, providing an electrical power (herein, a line power “LP”), at a given phase n. The ICB 102 further provides such switchable coupling to an electrical circuit 137 and, ultimately, to one or more loads 138. The ICB 102 provides an output power (herein, a switched power “SP”), at the given phase (n), to the electrical circuit 137.
Multiple LP feeds providing alternating currents, at different phases, may be received by an ICB 102 from the electrical source 109. For example, electrical power may be provided at a first-phase LP(1), a second LP(2), and/or a third phase LP(3). After undergoing controlled switching by the ICB 102, such electricity is provided to the electrical circuit 137 as switched/output power (SP) at one or more at a switched first-phase SP(1), a switched second phase SP(2), and/or a switched third phase SP(3). The ICB 102 may include a solid state switching module (“SSWM”) 104(n) for each phase of electrical power provided. In FIG. 1, a solid state switching module 104(1) for a single phase is depicted in solid lines. For multiple phase circuits, such as a three-phase circuit, SSWM 104(2) and 104(3) may be used and are shown in dashed lines.
For at least one embodiment of an ICB 102, the SP may be routed thru an electro-mechanical switch (“EMS”) 126(n) before being provided to the electrical circuit 137. An EMS 126(n) may be used for each phase (n) provided, as desired for a particular implementation. The EMS 126(n) is further described below. It is to be appreciated that an EMS 126(n) is often not used in conjunction with an ICR 152. A surge protection module 154 may be used. Surge protection modules are well known in the art. In FIGS. 1A and 1B, data lines between the power module 105 and elements are shown for the first phase, whereas data lines for any second and/or third phase components are not shown for purposes of clarity only.
A neutral “N” connection provides a return circuit path back from the electrical circuit 137 (and the load 138) to the electrical source 109, to a ground node, or otherwise. The neutral N may be coupled to a ground potential. A neutral sensor NS 124 may be used to monitor currents transmitted across the neutral connection.
The power module 105 provides monitoring, control, and other features and functions for use in adaptively controlling the electrical power provided by an electrical source 109 to the electrical circuit 137 and a load 138 via a given ICB 102 or ICR 152. By adaptively activating and deactivating one or more switches provided with each SSWM 104(n), the power module 105 may adaptively control, monitor, and regulate electrical power provided to the electrical circuit 137 and/or the load 138. Monitoring of electrical power, by the power module 105, may include use of one or more sensors including, but not limited to, “line power” sensors 120(n), “switched power” sensors 122(n), “relay power” sensors 156(n), “neutral” sensor NS 124, and temperature sensors (not shown). One or more of the line power, switched power, relay power, and/or neutral sensors may be configured to sense currents and/or temperatures. Temperature sensors may be provided separate and/or in conjunction with one or more of the line sensors 120(n), switched sensors 122(n), and/or relay sensors 156(n). As depicted by their absence in FIG. 1B, line power sensors 120(n) and switched power sensors 122(n) may not be used for at least one embodiment of an ICR 152, while relay power sensors 156(n) may not be used for at least one embodiment of an ICB 102. For other embodiments, (not shown), one or more line power sensors 120(n), switched power sensors 122(n), and/or relay power sensors 126(n) may be used interchangeably in an ICB 102 and/or in an ICR 152. Such sensors are further described below.
The power module 105 may include a high voltage (HV) domain 106 that is electrically separated form a low voltage (LV) domain 112 by an isolation barrier 116. A HV-LV communication link 118 facilitates communication of data between the HV domain 106 and the LV domain 112. Such communication link includes use of an HV Comm element 117, and an LV Comm element 119. Each of these components are described in further detail below.
Other elements of the systems 100 and 150 may include, but are not limited to, an AC/DC converter 128, a cooling element 130, an external communications module 132, an external control device 136, and a backup power module 140. Each of these components is described in further detail below.
LPS 120(n)/SPS 122(n)/RPS 156(n) and NS 124
For at least one embodiment for an ICB 101, a line power sensor (“LPS”) 120(n) and switched power sensor (“SPS”) 122(n) may be provided in a common packaging, module, die, or otherwise for a given phase (n) of line power LP(n). For other embodiments, one or more of the LPS 120(n) and/or SPS 122(n) may be provided in separate packaging, modules, dies, or otherwise from separate a given phase module 102(n).
An LPS 120(n), an SPS 122(n), and/or a relay power sensor (“RPS”) 156(n) may be combined in a common packaging, die, module or otherwise with one or more solid-state switches provided by a given SSWM 104(n). For example, and not by limitation, a given SSWM 104(n) may include a power field effect transistor (FET) that includes an integrated sensing FET (herein, a “senseFET”).
One or more of the LPS 120(n), SPS 122(n) and/or RPS 156(n) may be provided by use of one or more senseFETs. A senseFET may be configured provide corresponding sensor readings to HV controller 110. Such sensor readings may include one or more of currents, voltages, temperature, or other parameters to the power module 105.
When isolation is to be provided between the HV domain 106 and the LV domain 112, a senseFET may be configured to provide readings from the LPs 102(n) to the LV controller 110 by use of one or more isolated communication links, such as those described herein with regard to the HV-LV communication link 118. Further, an output senseFET may be configured to provide readings from an SPS 122(n) and/or from an RPS 156(n) to the LV controller 114 directly, such as when isolation is not needed, and/or by use of one or more isolating communication link components, when isolation is needed.
A neutral sensor NS 124 may be provided. The NS 124 may be provided in, with and/or separate from a given ICB 102. For at least one embodiment of an ICR 152, a neutral sensor is not utilized. An NS 124 may be provided in an electrical panel and configured to provide sensor readings to two or more phases located within an ICB 102 and using a common neutral node. The NS 124 may be configured to provide sensor readings of currents, voltages, or otherwise.
Each LPS 120(n) may be configured to perform, during power-on or otherwise, one or more self-test operations including, but not limited to, monitoring at least one characteristic of a given LP(n), such as currents and voltages provided to the ICB 102 by the electrical source 109 and for a given phase (n) prior to such electrical power flowing thru or being inhibited by solid-state switches provided by the SSWM 104(n). Each SPS 122(n) may be configured to monitor at least one characteristic of a given SP(n), such as currents and/or voltages for a given phase (n) after electrical power passes thru the switches utilized in the SSWM 104(n), and as such electrical power is output by the ICB 102 to the electrical circuit 137 and used by the load(s) 138. Each RPS 156(n) may be configured to monitor at least one characteristic of a given RP(n), such as currents and/or voltages for a given phase (n) after electrical power passes thru the switches utilized in the SSWM 104(n), and as such electrical power is output by the ICR 152 to the load(s) 138. Each of the LPS 120(n), the SPS 122(n), RPS 156(n), and NS 124 may utilize any known or later arising voltage and/or current sensing technologies, combinations thereof, or otherwise. LPSs 120(n), SPSs 122(n), and/or RPSs 156(n) may be include one or more temperature sensors. Amplifiers may be used, as desired for a given implementation of an embodiment of the present disclosure, to amplify signals provided by one or more of the sensors to the power module 105.
One or more, if not each, of the LPS 120(n), the SPS 122(n), the RPS 156(n), and the NS 124 may be configured to provide one or more sensor readings on a continuous, periodic, on demand, scheduled, or another basis. Readings from each such sensor may be communicated to a low voltage controller 112. Sensor readings for one or more of the LPS 120(n), SPS 122(n), RPS 156(n) and/or NS 124 may be provided on an isolated or non-isolated basis, as desired for any particular implementation of an embodiment of the present disclosure.
At least one of the LPS 120(n), the SPS 122(n), RPS 156(n), and the NS 124 may include use of a sense resistor. It is to be appreciated that a sense resistor commonly is accurate within three to five percent (±3% to ±5%), but provides no isolation, with high insertion losses. Sense resistors may be used, for example and not by limitation, for high bandwidth applications, such as those where switching is within the direct current to 10 MHz range. As used herein, low, medium, high and the like, as used to refer to a particular device characteristic and/or property, are determinable by a person having ordinary skill in the art by comparison with known properties of alternative sensors such as, but not limited to, the sensors identified herein.
At least one of the LPS 120(n), the SPS 122(n), RPS 156(n), and the NS 124 may include use of a Hall-Effect current sensor. The Hall-Effect current sensors may be contact or contact-less sensors, with accuracies respectively ranging within the one to five percent range (±1% to ±5%) for the former and within the five to ten percent range (±5% to ±10%) for the latter. Contact Hall-Effect current sensors may be used to provide, for example and not by limitation, medium level isolation, medium level insertion loss, and for use with high power needs. Switching within the direct current to 1 MHz range may be supported by contact Hall-Effect current sensors. Contactless Hall-Effect current sensors may be used to provide, for example and not by limitation, isolation, zero insertion loss, and for use with high power needs. Switching within the direct current to 100 kHz range may be supported by contactless Hall-Effect current sensors.
At least one of the LPS 120(n), the SPS 122(n), RPS 156(n), and the NS 124 may include use of current sense transformers. Current sense transformers may be used, for example and not by limitation, to provide accuracies within one to five percent range (±1% to ±5%), while providing isolation, zero insertion loss, requiring use of no power supply and supporting switching within the 50 Hz to 1 MHz range.
For at least one embodiment where current sensing accuracy within one percent (±1%) is desired, at least one of the LPS 120(n), the SPS 122(n), RPS 156(n), and the NS 124 may include use of Tunnel Magneto Resistance (TMR) current sensors. TMR current sensors may provide isolation, zero insertion loss, use of a low power supply, and support switching within the direct current to 1 MHz range.
Input/line LP, output/switched SP currents, and relay currents RP may be continuously monitored by respective LPS(n), SPS(n), RPS(n) (one for each phase used in an implementation) to detect whether a leakage current or other current anomaly is occurring within a given electrical circuit, for one or more phases (n). Monitoring for leakage currents and/or other anomalies may be performed, for example, by the LVC 114. When a leakage current is detected, the LVC 114 may instruct the HVC 110 to take appropriate action such as configuring the solid-state switches in the SSWMs 104(n) for the at fault phase and/or for all phase into an open-circuit configuration, or otherwise.

The gate driver 108 may be configured to the control operating states (open/closed) of the solid-state switches used in the SSWMs 104(n). The use of gate drive signals 302 to control transistors used in the solid-state switches and thereby voltages, currents and phases of electrical power ultimately provided to the load 138 are well known in the art and are not further described herein. Any such known or later arising switching protocols, methods, components, technologies, or the like may be used for one or more embodiments of the present disclosure. Further, it is to be appreciated that given the use of solid-state switches in the SSWM 104(n), voltages and currents may be provided at any desired voltage potential, current, or the like. Such voltages and currents provided may vary over time or on any other basis—as controlled by the gate drive signals 302 output by the gate driver 108 to the switches provided in the SSWM 104(n).
The gate driver 108 may be configured to receive control signals from the HVC 110 and based thereon, generate gate drive signals 302 which facilitate one or more electrical power management operations, such as wave-shaping. Such wave-shaping may be provided based on load conditions. Load conditions may be detected by the HVC 110 and/or the LVC 114. Wave shaping capabilities may be provided monolithically as an IC with a gate driver, as a multi-die package, as multiple ICs, or otherwise. For at least embodiment, wave shaping capabilities may be provided by, in or with use of one or more of the gate driver 108, the HVC 110, and/or the LVC 114.

Such motor operations may be based on one or more mathematical models, integrated measurement methods for motors and/or other loads electrical parameters, real-world testing, or otherwise.
For at least one embodiment where two or more phases (n) are to be controlled by the power module 105, the gate driver 108 may be configured to receive control signals from the HVC 110 and based thereon, generate gate drive signals 302, which facilitate other electrical power management operations, such as phase balancing. Such control signals may be generated using a balancing monitor (not shown) provided by one or more of the HVC 110 or the LVC 114. The balancing monitor may be configured to differentially compare current readings for each phase utilized for given circuit. Such current readings may be provided by the LPS(s) 120(n) and/or the SPSs 122(n) (for an ICB 102), and/or by the RPSs 156(n) (for an ICR 152). Results generated by the differential comparisons may be evaluated by a balance logic (not shown) to determine whether one or more of the phases (n) are out of balance. When an out of balance condition is detected, the controller (HVC 110 or LVC 114) facilitating the balance monitoring may be configured to generate one or more out of balance control flag signals which, when communicated to the gate driver 108, result in modifications to one or more gate drive signals provided to one or more of the SSWMs 104(n).
It is to be appreciated that gate drive signals may be provided at any time, based upon detection of a fault condition or otherwise, to facilitate any given operational consideration. For example, gate drive control signals may enable an electrical circuit 137 and/or a load 138 to be powered down in a safe and/or controller manner when a fault condition, such as a phase imbalance, is detected. Likewise, gate drive controls signals may be configured to facilitate other electrical power management operations including, but not limited controlled start-up of loads, minimal power modes (such as when a load is inactive), controlled non-fault condition power downs of loads, emergency condition power downs, or otherwise.
