Abstract:
1. A power conversion apparatus for an electric vehicle comprising: a converter unit that converts an alternating-current power into a direct-current power; an inverter unit that converts the direct-current power into an intended alternating-current power and supplies the intended alternating-current power to an electric motor that drives an electric vehicle; a housing that accommodates the converter unit and the inverter unit and a part of which is connected to ground; and an impedance element that is disposed inside the housing and that has an inductance component that suppresses a resonant current flowing between the converter unit and the inverter unit, wherein the impedance element is disposed at least at either one of in the converter unit at an output side of a converter main circuit included in the converter unit and in the inverter unit at an input side of an inverter main circuit included in the inverter unit.
