Abstract:
A power conversion apparatus includes a semiconductor module including a semiconductor device and a control circuit unit controlling the semiconductor module. The semiconductor module has main and subsidiary semiconductor devices connected in parallel. The control circuit unit performs control such that the subsidiary semiconductor device is turned on after the main semiconductor device is turned on, and the main semiconductor device is turned off after the subsidiary semiconductor device is turned off. The control circuit unit performs control such that, one of the turn-on and turn-off switching timings has a switching speed faster than that of the other of the switching timings. The semiconductor module is configured such that, at a high-speed switching timing, an induction current directed to turn off the subsidiary semiconductor device is generated in a control terminal of the subsidiary semiconductor device depending on temporal change of a main current flowing to the main semiconductor device.

Claim (Index 7):
The power conversion apparatus according to  claim 1 , wherein\n two semiconductor device pairs, each having the main semiconductor device and the subsidiary semiconductor device, are connected in series to each other, the control circuit unit has a short-circuit protection circuit configured to turn off any one of the semiconductor device of an upper arm side and the semiconductor device of a lower arm side when the semiconductor device of the other arm side is short-circuited, and the semiconductor module is configured such that the first induction current directed to turn off the subsidiary semiconductor device is generated in the control terminal of the subsidiary semiconductor device depending on the temporal change of the main current flowing to the main semiconductor device when the main semiconductor device is turned off.
