ABSTRACT:
A backup power supply for use with a power plant having a primary power supply that provides primary power to an AC bus for subsequent conversion to DC power and a method of providing backup power to the AC bus. In one embodiment, the system includes a battery charger/inverter, coupled to the AC bus and couplable to a battery, that operates in a normal mode to convert a portion of the primary power to charge the battery and operates in a battery backup mode to convert DC power from the battery to provide the backup power to the AC bus.
