A second power conversion device (17) converts power supplied from a voltage supply connected to the input side, and supplies power to a first electricity storage device (16). A first contactor (15) is turned on, and a smoothing capacitor (12) is charged with power that has been charged in the first electricity storage device (16). A control unit (18) controls a first power conversion device (11), and the first power conversion device (11) converts the power charged in the smoothing capacitor (12), and supplies thus converted power to a power generator (3). |
