Abstract
An apparatus includes a plurality of starter/generator subsystems connected in parallel to a voltage distribution bus and to an input power supply. Each of the subsystems includes a starter/generator unit (SGU) for providing torque for starting an engine when the apparatus is operated in an engine start mode, and for generating power when the apparatus is operated in a generator mode. In an embodiment, each subsystem includes a power conversion unit (PCU) connected to the respective SGU, and each PCU includes an inverter section for rectifying voltage generated by the SGU when the apparatus is operated in the generator mode and may provide AC excitation voltage to operate the SGU as a motor to support the engine start mode.
