Abstract:
1. A power and start system for use with an engine, the engine including a shaft, systems requiring AC power, and systems requiring DC power, the power and start system operating in at least a generate mode and a start mode, the power and start system comprising: an AC/DC starter/generator mechanically coupled to rotate in response to rotation of the engine shaft in generate mode to produce AC and DC power and to rotate the shaft of the engine when in start mode; a generator control unit electrically coupled to the AC/DC starter/generator and the systems requiring DC power; a start inverter configured to be coupled to a DC power source, the start inverter being coupled to the AC/DC starter/generator to provide power for start mode operation; a first controllable contactor coupled to the start inverter; a second controllable contactor coupled to the systems requiring AC power; and a third controllable contactor coupled to the systems requiring DC power.
