| abstract |
A power semiconductor switching element damage judging device, comprising: a resistor connected to a gate of the power semiconductor switching element; and both ends of the resistor when a predetermined voltage is applied to the gate of the power semiconductor switching element. A comparing unit that compares a detection voltage according to a voltage generated in the power supply with a reference voltage, and predicts that predetermined damage has been accumulated in the gate insulating layer of the power semiconductor switching element when the detection voltage exceeds the reference voltage. And a prediction unit that performs the calculation. [Selection diagram] Fig. 4 |
