Inverter-integrated electric compressor

Abstract

There is provided an inverter-integrated electric compressor which makes it possible to effectively suppress noise caused by a common mode current while achieving a size reduction. The inverter-integrated electric compressor includes an inverter device 3 which has upper and lower arm switching elements 13 and 16 and applies a three-phase AC output to a motor M. The inverter-integrated electric compressor injuries a control board which controls the switching of the upper and lower arm switching elements 13 and 16, and a bus bar assembly 22 provided to establish wiring among a battery 24, the control board, the upper and lower arm switching elements 13 to 18, and the motor M. A normal mode coil 40, a three-phase common mode coil 41, a ferrite core 42, reflux capacitors 43 and 44, and a snubber circuit 52 are arranged in the bus bar assembly 22.
