Problems solved by technology

[0007] However, it is necessary to separate the second housing part for housing high-voltage components such as common mode coils, normal mode coils, and smoothing capacitors, and a waterproof sealing material for the second housing part is required, so the number of parts increases. In addition, the size of the inverter-integrated electric compressor increases, and the degree of freedom in the layout of the inverter-integrated electric compressor decreases.

Abstract

The invention provides an electric vehicle restricting large development of an electric compressor. The electric vehicle (10) is provided with a power control unit (30) using a battery (18) to carry out driving control to a driven motor, an air-conditioned compressor (118), a conductive component (180) provided with branch points (181-185), so that one end is connected with the battery (18) side and the other end is respectively connected with a power conversion module (60) and the air-conditioned compressor (118). The power conversion module (60) is disposed in the power control unit (30) and is used for converting DC of the battery (18) to AC. Coils (117,200) are arranged between the branch points (181-185) and the air-conditioned compressor (118). The conductive component (180) and the coils (117,200) are arranged in the power control unit (30).

Description

technical field [0001] The present invention relates to an electric vehicle that suppresses enlargement of electric compressors and the like. Background technique [0002] Patent Document 1 described below describes a structure in which a first housing portion and a second housing portion are provided on the outer periphery of a housing of an inverter-integrated electric compressor, the first housing portion accommodates an inverter module, The inverter module includes a power system substrate on which semiconductor switching elements and the like are mounted, and a CPU substrate on which a control communication circuit is mounted. Common mode coils, normal mode coils, smoothing capacitors and other high voltage components installed on the device. [0003] In this way, the electromagnetic noise emitted from high-voltage components such as the common mode coil, the normal mode coil, and the smoothing capacitor is shielded by the second housing portion, so that the transmissi...
