摘要： A drive circuit that controls a switching device ON/OFF and a soft cutoff command circuit that gradually decreases the gate terminal voltage of the switching device when short circuit of the switching device is detected. Additionally, an ON-pulse retention command circuit retains the output of the drive circuit ON when the gate terminal voltage is judged to have exceeded a specified value by a gate voltage judgment comparator that detects the gate terminal voltage of the switching device.

摘要： A collector voltage of a power management semiconductor device is detected by a first comparator, and when the detected collector voltage exceeds a first reference voltage, the first comparator outputs a first detection signal. Furthermore, a gate voltage of the power management semiconductor device is detected by a second comparator, and when the detected gate voltage exceeds a second reference voltage, the second comparator outputs a second detection signal. The second reference voltage is a minimum gate voltage for feeding a rated power to the power management semiconductor device or over, and less than a line power voltage of a drive circuit of the power management semiconductor device. When both the first detection signal and second detection signal are being outputted, the gate voltage is reduced by a gate voltage reduction means so as to protect the power management semiconductor device from overcurrent and overvoltage.

摘要： In an inverter maintenance system, while an inverter of a user, a user support server of maker, and also, a portable telephone capable of accessing to a Web server are employed, such information required to maintain/manage the inverter is transferred/received by way of the portable telephone. Thus, various sorts of requests can be accepted by both the user support server and the Web server.

摘要： A power converter includes a shunt resistor constituted by a shunt resistance and a plurality of main electrodes made of a sheet-like resistive material. In the shunt resistor, plates lower in volume electric resistivity than the resistive material, higher in thermal conductivity than the resistive material and thicker in thickness than the resistive material are fixedly attached by solder, to the side surfaces of the main electrodes opposite to the side surfaces with which the main electrodes are fixedly attached to an insulating layer. At least one plate main electrode for electrically connecting with main circuit wiring is provided in each of the plates. At least one constricted portion is formed between each of the plate main electrodes and the shunt resistance. Plate detection electrodes for detecting a voltage between the opposite ends of the shunt resistance is provided on the plates near the shunt resistance portion.
