Abstract
A DC-link, variable speed constant frequency power system is provided with an auxiliary DC output. The system includes a variable speed generator for producing a DC voltage on a pair of DC-link conductors. When the generator is operated in its normal speed range, an inverter converts the DC voltage to a constant frequency AC voltage. When the generator is operated at a speed which is below its normal speed range or when an external auxiliary output command signal is received, the DC-link conductors are switched to an auxiliary output line and the DC-link voltage is regulated to maintain the desired auxiliary output voltage level.
