  • Publication number: 20240145152
    Abstract: A motor-driven compressor includes an inverter device. The inverter device includes a common mode choke coil. The common mode choke coil includes an annular core, two windings wound around the core, and an annular conductor that covers the two windings. The conductor is divided into a first metal plate and a second metal plate, which are combined to form an annular shape such that induced current flows in a circumferential direction of the conductor so as to hinder changes in leakage magnetic flux from the core. The second metal plate is thermally connected to the housing. The first metal plate is thermally connected to the second metal plate. At least one of an electrical resistance value or a thermal resistance value in a current path of the induced current is lower in the second metal plate than in the first metal plate.
