Abstract:
A power controller for controlling an engine-driven generator, the controller comprising:a conductor defining a DC bus for conducting electrical DC power at a DC bus voltage of at least 120 volts; a bi-directional DC-DC converter in electrical communication with the DC bus and a battery and constructed to transfer electrical power from the DC bus to the battery to charge the battery, and from the battery to the DC bus; a rectifier in electrical communication with the DC bus and the generator and constructed to rectify electrical power from the generator and to supply the rectified power to the DC bus; an inverter in electrical communication with the DC bus and constructed to convert DC bus electrical power to AC electrical power and to supply the AC power to an output connector; and an AC-DC converter in electrical communication with both the DC bus and an input connector, the AC-DC converter constructed to convert AC electrical power, supplied via the input connector, to electrical power for the DC bus, wherein the controller is capable of motoring the engine-driven generator using either the electrical power from the AC-DC converter or the electrical power from the battery.
