Example Embodiment

[0026] Hereinafter, an embodiment of the power conversion device of the present invention will be described with reference to the drawings.

[0027] The power conversion device of this embodiment controls the power transfer between the motor and the battery. For example, the power conversion device is mounted on an electric vehicle or the like. Electric vehicles include electric vehicles, hybrid vehicles, and fuel cell vehicles. Electric vehicles are driven by batteries as a power source. Hybrid vehicles use batteries and internal combustion engines as power sources for driving. Fuel cell vehicles use fuel cells as a power source for driving.

Abstract

The invention provides a power conversion device capable of improving wiring efficiency and improving space efficiency and layout characteristics when it is attached to another device. The power conversion device (1) includes a plurality of semiconductor modules (61), a capacitor unit (23), and a conductor group (67) including a positive electrode bus bar and a negative electrode bus bar. When viewed from a direction in parallel to a placement surface (SA), the plurality of semiconductor modules (61) and the capacitor unit (23) are arranged to overlap each other in the orthogonal direction orthogonal to the placement surface (SA). The conductor group (67) extends along a direction in parallel to the placement surface (SA) in a range in which the positions of the plurality of semiconductormodules (61) and the capacitor unit (23) overlap each other in the orthogonal direction in a state in which the positive electrode bus bar and the negative electrode bus bar face each other, and connects the semiconductor modules (61) and the capacitor unit (23).

Description

technical field [0001] The present invention relates to power conversion devices. Background technique [0002] Conventionally, a drive unit for a vehicle has been known, which has a drive unit housing for accommodating a generator and an electric motor, and a power control unit mounted in the drive unit housing (for example, refer to JP-A-2016-140198 ). In this vehicle drive unit, the power control unit includes two inverters respectively connected to a generator and a motor, a control unit for controlling the two inverters, a current sensor, and the like in a unit case. The outer shape of the drive unit case is formed in a cylindrical shape, and the drive unit case is arranged such that the axial direction becomes the vehicle width direction. The outer shape of the unit case is formed in a box shape, and the unit case is arranged to be placed on the upper surface of the drive device case in the vertical direction of the vehicle. [0003] However, according to the vehicl...
