An object is to provide a duplex power supply for auxiliary machines. A power supply device includes a switching section that is connected to a direct-current link between a generator-side inverter and a grid-side inverter via an auxiliary machine power inverter for converting direct-current power supplied from the direct-current link into alternating-current power to form a first path, that is connected somewhere between a power-converting section and a utility grid to form a second path, and that is connected to auxiliary machines to form a third path, and the switching section switches between connection of the third path to the first path and connection of the third path to the second path.
