<p>A redundant power supply for an auxiliary machine can be implemented. A power supply device forms a first route (A), a second route (B), and a third route (C) and is provided with a switching unit (15), wherein: the first route (A) is formed by being connected to a DC link (12) between a power generator side inverter (11) and a power system side inverter (13) via an auxiliary power inverter (14) for converting DC power supplied from the DC link (12) to AC power; the second route (B) is formed by being connected between a power conversion unit (5) and a power system (7); the third route (C) is formed by being connected to the side of an auxiliary machine (8); and the switching unit (15) switches between the connections between the third route (C) and the first route (A) and between the third route (C) and the second route (B) in response to the request from the side of the power system (7).</p> |
