    摘要: An electric power converter includes a semiconductor module that has a semiconductor element therein, a cooler that cools the semiconductor module, a circuit board provided with a semiconductor control circuit that controls the semiconductor module, a capacitor electrically connected to the semiconductor module, and a quick discharge resistor for discharging an electric charge accumulated in the capacitor. The circuit board is provided with a discharge control circuit that controls a current that flows into the quick discharge resistor. The semiconductor module, the cooler, the capacitor, and the quick discharge resistor are disposed on one major surface of the circuit board.

    摘要: A capacitor unit includes a capacitor having a positive electrode and a negative electrode, a positive bus bar, a negative bus bar, a sealing resin, an insulator. The positive bus bar and the negative bus bar are respectively connected to the positive electrode and the negative electrode. The sealing resin seals the capacitor, a part of the positive bus bar, and a part of the negative bus bar. The insulator is located between the positive bus bar and the negative bus bar. The insulator includes a recess recessed from either surface of the insulator facing the positive bus bar or the negative bus bar. At least a part of the recess is exposed from the sealing resin.

    摘要: A power conversion device includes an electronic component, a cooler, a housing, protruding pipes, and annular seal members. Each of the seal members includes a seal body portion interposed between a corresponding one of the protruding pipes and the housing, and a flange portion extending outward from the seal body portion in a radial direction and contacting an outer surface of the housing from an axial direction. The housing includes a peripheral wall surface formed to surround the flange portion from an outer peripheral side, and an annular groove portion formed along an outer peripheral edge of the flange portion inside the peripheral wall surface. The peripheral wall surface is formed to extend outward, in the axial direction, from an axial contact surface of the housing contacted by the flange portion.

    摘要: A sealing structure includes: a case that stores an in-vehicle electronic component and has an opening; and a first cover member that covers the opening of the case. The case includes: an protrusion member that has a sealing surface protruded to surround the opening; and a rib that is protruded on an opposite side of the opening with the protrusion member interposed therebetween. The rib has a discharge surface that is connected to the sealing surface of the protrusion member. The first cover member has an extension member that extends along the rib. The discharge surface of the rib is located to be lower than the sealing surface of the protrusion member while the case is arranged with the opening facing upward, and the extension member of the first cover member extends to be lower than the discharge surface of the rib.

    摘要: A reactor cooling device includes a housing, a reactor arranged in the housing, and a rotating body which is rotationally located below the reactor in the housing. The rotating body and the reactor are located so as to at least partially overlap with each other in a previously selected one of turning radius directions of the rotating body. A part of the rotating body is immersed in the coolant stored in the housing. The reactor cooling device is configured to cause a part of the coolant splashed by the rotation of the rotating body to be in contact with the reactor to thereby cool the reactor.

    摘要: A cover includes a cover body and an interlock connector. The cover body covers an opening provided in a case of a power conversion device and is electrically conductive. The interlock connector is electrically connectable to a receptacle connector provided inside the case. A noise shielding layer and a low conductivity layer are formed between the cover body and the interlock connector. The noise shielding layer is electrically conductive. The low conductivity layer is closer to the cover body than the noise shielding layer is, and is less electrically conductive than the cover body and the noise shielding layer.
