Abstract
A motor-driven compressor is formed integrally with a compression portion and a motor for compressing refrigerant. The motor-driven compressor includes a drive circuit for controlling the driving of the motor. The drive circuit is incorporated into a refrigerant suction side portion of the motor-driven compressor. The motor-driven compressor may be made small and inexpensively, as well as the total system which includes the drive circuit. The assembly of the system may also be more easily facilitated. Further, electromagnetic radiation from an inverter of the drive circuit may be shielded.
