Latest Patents

One of his latest inventions is an electric compressor that includes a compression part, an electric motor, an inverter device, and a housing. The inverter device features an inverter circuit, a noise reduction unit, and a circuit board. The noise reduction unit comprises a common mode choke coil and a smoothing capacitor. The common mode choke coil consists of an annular core, a pair of winding wires, and an annular electrical conductor. The electrical conductor is divided into a first metal plate and a second metal plate in a circumferential direction. The first metal plate is thermally coupled to the housing, while the second metal plate is electrically connected to the first metal plate. Notably, the electrical resistance value of the first metal plate is larger than that of the second metal plate.

Another significant patent is for an in-vehicle motor-driven compressor. This invention includes a common mode choke coil with an annular core that has a through-hole, a first winding, and a second winding wound around the core, along with an annular conductor. The second winding is positioned opposite the first winding while being spaced apart. The conductor surrounds both windings and the core. The core is designed to be symmetrical with respect to at least one symmetry axis when viewed from the front. The first winding is located on one side of the symmetry axis, while the second winding is on the other side, ensuring that the symmetry axis is situated between them. The core also features an exposed section that is not covered by the conductor.
