    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.

    Abstract: A vehicle inverter device is configured to convert DC power to AC power. The vehicle inverter device includes a circuit having switching elements and a noise reducer. The noise reducer is provided on an input side of the circuit and is configured to reduce common mode noise and normal mode noise contained in the DC power. The noise reducer is configured by a common mode choke coil, which includes a core, a first winding wound about a first winding portion of the core, and a second winding wound about a second winding portion of the core.

    Abstract: An on-vehicle motor-driven compressor includes an inverter device having a noise reducer. The noise reducer includes a common mode choke coil. The common mode choke coil includes an annular core, first and second windings wound around the core, the second winding being spaced apart from and opposed to the first winding, an annular conductor that extends over the first winding and the second winding and covers the core, and an insulating layer located between an inner circumferential surface of the conductor and outer surfaces of the first winding and the second winding. The conductor is tubular and belt-shaped. The core includes an exposed portion that is not covered by the conductor. The insulating layer is tubular and belt-shaped. An entirety of the conductor is arranged within a range between opposite ends of the insulating layer.

    Abstract: An on-board electric compressor that comprises: a housing; a compression unit; an electric motor; and an inverter device. The inverter device comprises: an inverter circuit that converts direct current power to alternating current power; and a noise reduction unit that is provided on an input side of the inverter circuit and that reduces common mode noise and normal mode noise that are included in the direct current power The noise reduction unit comprises: a common mode choke coil; and a smoothing capacitor that, in cooperation with the common mode choke coil, constitutes a low pass filter circuit. The common mode choke coil has: a core that has a first core part and a second core part; a first winding that is wound around the first core part; and a second winding that is wound around the second core part.

    Abstract: A common-mode choke coil includes a loop-shaped core, a cover made of a conductor covering at least part of the core, a first winding wound around an outer surface of the cover, and a second winding wound around the outer surface of the cover. The cover includes a first region around which the first winding is wound, a second region around which the second winding is wound, and two connection regions that connect the first region and the second region to each other in a circumferential direction. The cover has first and second slits in an inner circumferential surface. The first slit extends such that the first region is non-continuous with respect to a winding direction of the first winding. The second slit extends such that the second region is non-continuous with respect to a winding direction of the second winding.

    Abstract: An on-board fluid machine includes a housing configured to allow fluid to flow into the housing, an electric motor accommodated in the housing, and a driver that is supplied with DC power and drives the electric motor. The driver includes a low-pass filter circuit and an inverter circuit. The low-pass filter circuit includes a common mode choke coil and a capacitor. The driver further includes a damping unit located at a position where magnetic field lines produced by the common mode choke coil generate eddy current.
