Title: Current limit circuit
IPC: H01L29/78
Filed: 1992-03-12
Abstract: PURPOSE:To improve the relation of trade-off between a loss and an oscillation characteristic by setting a gate voltage of an output current detection IGBT to be lower than a gate voltage of an output IGBT in the current limit operation. CONSTITUTION:A collector of a main IGBT(isolation gate bipolar transistor) 1 as an output element is connected to a load. A sense IGBT 2 being its current branch element and a resistor 5 form an output current detection means. A base of a bipolar transistor(TR) 6 as a limit means is connected to an emitter of the sense IGBT 2. A gate voltage Vg of the main IGBT 1 is divided by the resistor 3 and the bipolar TR 6 to obtain a gate voltage Vgs of the sense IGBT 2. That is, the relation of Vgs<Vg is set. Thus, the gate voltage is decreased to a prescribed voltage by increasing an output voltage only a little. Thus, a minimum output voltage for operating a current limit is increased without causing oscillation and the loss is reduced.

Abstract: PROBLEM TO BE SOLVED: To eliminate errors due to temperature variations in an operation environment and to ensure stabilized operation by improving the processing speed of AD conversion. SOLUTION: The amplification factor of an analog input voltage is specified with binarized data obtained through comparison between the amplification value of the sequential analog input voltage and a reference voltage. At the start of operation, the binarized data is varied sequentially to make an adjustment based on the deviation of the amplified analog input voltage from a nearby value of the reference voltage so that the amplified analog input voltage is close to the reference voltage, and the binarized data are outputted as digital data. The reference voltage for comparing the amplification factor of the analog input voltage is amplified with a fixed value, and in the process wherein the analog input voltage is amplified, errors due to temperature variations, etc., are canceled as much as possible.  Further, the inputted reference voltage is amplified according to the amplification factor determined on the basis of the digital input value and reverse conversion for using the amplification result as an analog output is performed.

A curve above the afore-mentioned oblique line shows TDN amount to be derived of a calf which is growing, and a curve above the former shows TDN amount of a grown-up cow which is in the final two or three months of pregnancy. A curve on the right of the oblique line shows DCP amount to be derived in the same way, and furthermore a curve on the right of the former shows DCP amount to be derived concerning a cow which is pregnant. B is that which has added the nutrition amount of a grown-up cow to A, and becomes a fixed plate. C is a plan of a slide rule.

Abstract: PURPOSE:To prevent the switch element of a flux pump from burning out by forming the switch element of wire materials bent several times in the direction perpendicular to a shifting-magnetic-field direction. CONSTITUTION:The switch element is constituted by connecting several wire materials 12 in parallel and each wire material 12 is bent several times in the direction perpendicular to the shifting direction of the shifing magnetic field.

The effective length of wire material 12 participating in the shifting magnetic field becomes longer, and consequently the highly-efficient excitation of coil 11 by the shifting magnetic field can be realized.
