  • Electric power conversion device and surge voltage suppressing method
    Patent number: 9124270
    Abstract: To provide an electric power conversion device that converts direct current power supplied from a direct-current power supply into alternating current power, the electric power conversion device includes six switching elements constituted by a voltage-driven transistor that uses a wide bandgap semiconductor and a diode, and a drive circuit that controls a voltage for driving the transistor at a time of turning off the switching elements based on a predetermined voltage profile specifying that the transistor is operated in a non-linear region.
