摘要:
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.

In one technique of the present invention, DC electric power from a DC bus is inverted to provide AC electricity to one or more electrical loads, and AC power from a variable speed generator is rectified to provide a first variable amount of electric power to the DC bus. This technique also includes determining power applied to the electrical loads, and dynamically controlling the amount of power supplied from the generator and an electrical energy storage device in response to the power applied to the loads.

An apparatus includes a vehicular electric power generation system comprising a variable speed internal combustion engine, a first variable speed electric power generator driven by the engine, a second variable speed electric power generator driven by the engine, a first inverter to receive electric power from the first generator a provide a first controlled electric output, a second inverter to receive electric power from the second generator and provide a second controlled electric output, and a controller coupled to the engine. The controller is responsive to variation in electrical loading of the first inverter and the second inverter and a degree of electrical load imbalance between the first inverter and second inverter to provide one or more engine control signals. The engine is responsive to the one more engine control signals to change rotational operating speed to adjust for the variation in electrical loading and the degree of electrical load imbalance.

An electric power system includes an engine, a generator driven by the engine, an electrical energy storage device, power control circuitry coupling the generator and storage device together, and a processor coupled to the circuitry. The generator provides variable AC power and the storage device provides variable DC power to the circuitry. The processor executes operating logic to provide control signals to the circuitry to operate the generator at a first speed to provide a first level of AC electricity, increase the DC power provided from the storage device to increase the AC electricity to a second level, increase operating speed of the generator from the first speed to a second speed greater than the first speed, decrease the DC power from the storage device as the operating speed of the generator increases, and limit acceleration of the operating speed to reduce perception of a speed change.
