Abstract
An inverter that drives a motor and a noise filter are arranged on a surface of a motor housing, and the inverter and the noise filter are integrated with the motor housing. The noise filter reduces a common-mode current generated by a switching operation of the inverter to flow out to a side of a three-phase power supply through the motor housing.

26. An inverter comprising:
-
an insulating layer that is formed on a flat surface of a motor housing; a conductor pattern that is formed on the insulating layer; a semiconductor chip in which at least a switching element is formed and that is, in a bare-chip state, integrated with the motor housing through the conductor pattern; and a noise filter that reduces a common-mode current, which is generated by a switching operation of the inverter, to flow out through the motor housing, wherein the motor housing is connected to ground potential, and one terminal of the noise filter is electrically connected to the motor housing. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
