Abstract: An object is to reduce a current detection error of a current sensor while suppressing upsizing of a power conversion device equipped with the current sensor. A power conversion device includes a power conversion circuit; a conductor to transmit current to the circuit; and a coreless current sensor to detect the current. The coreless current sensor includes: a magnetic field detection portion; and a shield portion facing the magnetic field detection portion. The conductor includes: a first conductor portion that passes through a space between the magnetic field detection portion and shield portion; and a second conductor portion connected to the first conductor portion via a first bent portion, and the first bent portion is formed such that the space between the magnetic field detection portion and shield portion is not disposed in a direction perpendicular to a face of the second conductor portion closest to the shield portion.

Abstract: A power converter configured to be mounted on an electrically driven vehicle comprises a control board that controls a power module including a semiconductor device, a connector provided on the control board so as to be connected to an external controller, a strong electric component arranged so as to overlap the control board, and a housing that houses the control board and the strong electric component. A bottom portion of the housing is formed to swell in a convex-shaped manner, a part of the strong electric component is housed in an area of the housing that swells in the convex-shaped manner, and the strong electric component is formed so that a projection area thereof to the overlappingly arranged control board is smaller than a surface area of the control board. The connector is arranged in an area of the control board broader than a projection plane of the overlappingly arranged strong electric component to the control board.

Abstract: An electronic component casing includes: an inclined portion that projects from an upper surface so as to increase in height gradually from one side; a step portion that descends as a continuation of an upper end of the inclined portion or descends via a plane connected to the upper end; and a planar portion connected to a lower end of the step portion.

Abstract: The arc-type evaporator of the present invention includes an anode and a cathode for generating arc discharging, a trigger electrode and a gas supply pipe. The trigger electrode is contacted with the cathode to cause a first spark, and thereafter is separated from the cathode to occur the arc discharge between the anode and the cathode. The gas supply pipe is provided independently of the trigger electrode, and supplies the cathode a reactive gas which reacts with a substance forming the cathode to produce a chemical compound. The gas supply pipe includes a gas blow-out port formed in the neighborhood of the side portion or rear side portion of the cathode to face the cathode. The reactive gas is supplied from the gas blow-out port to an area including the front surface of the cathode.
