ABSTRACT:
A hybrid power source includes a constant speed drive having an input coupled to a prime mover which develops variable speed motive power, an output driven at a substantially constant speed and a speed compensation link which transmits motive trim power at a magnitude determined by the speed of the prime mover. A first generator is coupled to the output of the constant speed drive and develops constant frequency AC power for AC loads. A second generator is coupled to the speed compensation link and is driven by the motive trim power such that the second generator develops power for DC loads and frequency insensitive loads wherein the power developed by the second generator is at a frequency which varies in accordance with the magnitude of the trim power.
