Use of a magnetic core in a power converting device for an electric vehicle

摘要

The object is to effectively reduce the resonant current flowing inside a converter unit and an inverter unit in a power conversion apparatus for an electric vehicle. The power conversion apparatus includes a converter unit (20) that converts an alternating-current power into a direct-current power, an inverter unit (60) that converts the direct-current power into an intended alternating-current power and supplies the intended alternating-current power to an electric motor (90) that drives an electric vehicle, a housing (80) that accommodates the converter unit (20) and the inverter unit (60) and a part of which is connected to ground, and a magnetic core (70) that is disposed inside the housing (80) and that suppresses the resonant current flowing between the converter unit (20) and the inverter unit (60).
