Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress conduction noise which flows out to a system power line, by reducing a common-mode current which leaks to the ground via the floating capacitor of a motor, in a power converter system equipped with an inverter device and a motor driven by the inverter device. SOLUTION: Each phase of wiring which connects the input part of an inverter device in the power converter system to a system power source is connected to the radiator of the inverter device, using a grounding capacitor, and the motor connected to the output part of the inverter device is accommodated, as well as; a frame connected electrically with the radiator is connected to grounding by using an impedance element.
