Abstract:
A power semiconductor module includes an insulated-gate type power semiconductor device, and a drive circuit controlling a gate voltage applied to the power semiconductor device in accordance with an input signal to drive the power semiconductor device so as to turn ON and OFF. The drive circuit includes a variable resistance circuit changing the gate voltage to the power semiconductor device, and a short-circuit state detecting circuit which maintains the resistance value of the variable resistance circuit to be a predetermined value at the time of a normal operation of the power semiconductor device, and which increases the resistance value of the variable resistance circuit so as to be greater than the predetermined value when a short-circuit state of the power semiconductor device is detected to suppress an oscillation in the power semiconductor device.

Claim (Index 6):
The power semiconductor module according to  claim 1 , wherein:\n the resistance value of the variable resistance circuit at the time of the normal operation of the power semiconductor device is set based on a loss of the power semiconductor device and a voltage surge thereof; and the resistance value of the variable resistance circuit to suppress an oscillation in the power semiconductor device is set so as to decrease a Q value of an oscillation circuit in the power semiconductor module.
