The present invention is provided with a DC inductor (13), a smoothing capacitor (17), an inrush current prevention circuit (15), an inverter (19), and an inverter substrate (45). The inrush current prevention circuit (15) is provided with: the DC inductor (13); relays (23, 27, 29) that open/close to the smoothing capacitor (17); and an inrush current prevention resistor (25) connected to the relay in parallel. The inverter substrate (45) performs an operation that decelerates a motor (7) that is driven by the inverter (19) and an operation that closes the relays (23, 27, 29) when the inverter (19) is abnormal. |
