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 1):
A power conversion apparatus comprising:\n a main semiconductor device and a subsidiary semiconductor device that are connected in parallel to each other and undergo switching operations, wherein the main semiconductor device and the subsidiary semiconductor device are controlled so that at least one of first and second conditions is met, the first condition being that a first turn-on timing at which the main semiconductor device is switched from an off-state to an on-state and a second turn-on timing at which the subsidiary semiconductor device is switched from an off-state to an on-state are different from each other, the second condition being that a first turn-off timing at which the main semiconductor device is switched from an on-state to an off-state and a second turn-off timing at which the subsidiary semiconductor device is switched from an on-state to an off-state are different from each other, and a first induction current directed to turn off the subsidiary semiconductor device is generated in a control terminal of the subsidiary semiconductor device depending on a temporal change of a main current flowing to the main semiconductor device.
