Abstract:
A common mode noise reduction apparatus includes a power converter that supplies electric power to a load; a housing that houses the power converter; a common mode inductor arranged between the power converter and the load; a power wire that passes through the common mode inductor and connects the power converter to the load; a grounding wire that passes through the common mode inductor and connects the housing and a bus of the power converter to ground potential on the load side; a first impedance element provided on the grounding wire between the load and the housing; and a second impedance element provided on the grounding wire between the bus of the power converter and the load.
