Abstract:
    A power supply apparatus for a line connection type fuel cell system includes a power converter system (PCS) control power supply which generates PCS control power from line power, a balance of plant (BOP) power supply which generates BOP power from line power, a regulator which generates PCS control power from the BOP power, a first switching unit switched by a control signal, which directs the line power to one of the PCS control power supply and the BOP power supply, a second switching unit switched by a control signal, which selects an output of one of the PCS control power supply and the regulator to provide PCS control power, and a controller which controls switching of the first and second switching units in response to a starting command.
