Abstract
An electric power system includes a variable speed generator driven by an engine and an electrical energy storage device. The generator and the storage device are coupled to a variable voltage DC bus. An inverter converts DC electricity from the DC bus to AC electricity for one or more electrical loads. A detector is included to monitor electric current provided to the DC bus by the storage device and provide a corresponding signal. Control circuitry is responsive to this signal to regulate power output from the storage device to the DC bus.
