Abstract

A power semiconductor module includes at least one upper arm provided between a positive electrode line and a node and including a power semiconductor device and a freewheeling diode connected in parallel, at least one lower arm provided between a negative electrode line and the node and including a power semiconductor device and a freewheeling diode connected in parallel, and a snubber circuit provided between the positive electrode line and the negative electrode line. The snubber circuit includes a snubber capacitor and a snubber resistor connected in series. At least one control terminal outputs a voltage representing the temperature of the snubber resistor or a voltage related to the temperature of the snubber resistor to a driver that drives the power semiconductor device.
