Abstract: In a power converter, a control circuit has a speed adjustment resistor that limits a control current to adjust a switching speed of each of first and second switching elements. The speed adjustment resistor has a resistance that varies depending on a voltage at the control electrode of each of the first and second switching elements. A feedback route connects between the control electrode of the first switching element and the control electrode of the second switching element. The feedback route has a resistance that is set to be lower than a value of the resistance of the speed adjustment resistor during a predetermined Miller period of each of the first and second switching elements.

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.

Abstract: In a power conversion device, first-phase semiconductor modules are successively arranged in a first direction to form a part of a first row. Second-phase semiconductor modules are successively arranged in the first direction to form a part of a second row while facing the first-phase semiconductor modules. Third-phase semiconductor modules are arranged in a second direction so that one of the third-phase semiconductor modules forms a part of the first row and another of the third-phase semiconductor modules forms a part of the second row. The first row and the second row have surfaces facing each other and from which output terminals protrude. Each of output conductors extends from a connected portion of an output terminal in a direction away from the third-phase semiconductor modules.
