A power converter () comprising components of a power converter circuit, the components including switching elements (to), smoothing capacitors (to), and circuit boards (and) on which drive circuit parts for driving the switching elements are mounted, wherein the components are housed in a case (), input power is converted and output through high-voltage terminals (to), and the high-voltage terminals (to) and the circuit boards (and) are provided in a common plane area (E).

Power converter

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.
