Abstract:
An electric compressor includes a compression part, an electric motor, an inverter device, and a housing. The inverter device includes an inverter circuit, a noise reduction unit, and a circuit board. The noise reduction unit includes a common mode choke coil and a smoothing capacitor. The common mode choke coil includes an annular core, a pair of winding wires, and an annular electrical conductor. The electrical conductor is split into a first metal plate and a second metal plate in a circumferential direction. The first metal plate is thermally coupled to the housing. The second metal plate is electrically connected to the first metal plate. An electrical resistance value of the first metal plate is larger than that of the second metal plate.
