To suppress resonance operation in a DC unit to which an inverter circuit and a DC-DC converting circuit are connected, a surge voltage generated upon switching of the DC-DC converting circuit and unbalance of load current between phases, and to realize stable control of the inverter circuit and the DC-DC converting circuit. By configuring the inverter circuit and the DC-DC converting circuit which configure an electric power conversion system within the same unit along with a shared capacitor at a DC input side, variation in wiring inductance between the inverter circuit and the DC-DC converting circuit and circuit inductance between the phases is reduced.
