USING AC AND DC GENERATORS WITH CONTROLLERS AS A REGENERATIVE POWER BURN OFF DEVICE

摘要

A power generation device for a utility vehicle having a battery source, a logic/driver module operably coupled to the battery source and capable of outputting power to a motive drive system, an internal combustion engine capable of outputting a mechanical driving force, and a generator system operably coupled to the internal combustion engine and electrically coupled to the logic/driver module. The generator system is capable of operating as a generator in response to the mechanical driving force of the internal combustion engine, thereby outputting electrical energy to the logic/driver module, and further is capable of operating as an electric motor in response to input of electrical energy from the logic/driver module. Between a first voltage and a second voltage, the output of the generator is reduced. Between the second voltage and a third voltage, the generator output is reduced to zero and the internal combustion engine is reduced to idle.
