Abstract
Power system and method for providing electrical power are provided. The system includes a traction system and auxiliary equipment coupled to a power bus. The traction system includes one or more electromotive machines having a first type of stator winding that provides protection relative to voltage spikes expected at the traction stator under a first voltage level appropriate for the traction system. The auxiliary equipment includes one or more electromotive machines having a second type of stator winding that provides protection relative to spikes expected at the auxiliary stator under a second voltage level lower than the first voltage level. Inverter circuitry is coupled to drive the auxiliary equipment, and signal-conditioning circuitry is provided to attenuate voltage spikes produced by the inverter circuitry. The power bus is operated at the first voltage level, and the voltage spike attenuation is sufficient to protect the auxiliary stator.
