Abstract: An inverter module according to an embodiment of the present invention comprises: a high voltage circuit unit which generates an inverter control voltage and a motor driving voltage by using a first DC voltage; a high voltage circuit pattern which electrically connects the high voltage circuit unit; a low voltage circuit unit which communicates with an external device by using a second DC voltage having a smaller magnitude than the first DC voltage; and a low voltage circuit pattern which electrically connects the low voltage circuit unit. The high voltage circuit pattern and the low voltage circuit pattern are spaced apart from each other.

Abstract: Disclosed herein is a motor-driven compressor with an inverter that is connected with an external power source via a connector part and controls a driving part which drives a compressing part to compress fluid. A printed circuit board is provided between the connector part and the driving part. Thus, noise transmitted from the driving part to the connector part is reduced, so that it is possible to minimize the transmission of the noise to an external power source.
