    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, each of semiconductor modules of a layered body includes a body portion incorporating a plurality of switching elements and a plurality of power terminals protruding therefrom. The semiconductor modules include upper-arm switching elements and lower-arm switching element that are alternately layered in a layering direction of the layered body. A capacitor is disposed on one side of the layered body and a current sensor is disposed on an opposite side of the layered body, in an orthogonal direction orthogonal to both a protruding direction of the power terminals and the layering direction. Each of the semiconductor modules includes, as the power terminals, two collector terminals connected to a collector electrode of the switching element and one emitter terminal connected to an emitter electrode of the switching element, and the emitter terminal is disposed between the two collector terminals in the orthogonal direction.

    Abstract: A power converter includes an inverter, a converter, an electrical-machine busbar, an electrical-machine sensor, an electrical-machine-sensor housing, a converter, a converter busbar, a converter-sensor housing. The inverter supplies a three-phase alternating current to a rotating electrical machine. The converter converts a voltage between a direct current power supply and the inverter. The electrical-machine busbar passes a current between the inverter and the rotating electrical machine. The electrical-machine sensor detects the current flowing through the electrical-machine busbar based on a magnetic field. The electrical-machine-sensor housing accommodates the electrical-machine sensor and the electrical-machine busbar together. The converter sensor detects the current flowing through the converter based on a magnetic field. The converter-sensor housing is disposed apart from the electrical-machine-sensor housing, and accommodates the converter sensor and the converter busbar together.
