Abstract
A hybrid power-generator system includes an engine, an electric generator, first and second rectifiers, first and second DC-DC voltage converters, a DC bus, an inverter, and one or more controllers. The system provides a unique method of joining two power sources such that the relative proportion utilized can be changed to any value seamlessly, such as to avoid daily and/or seasonal variations in utility charges. Since the AC output portion of the circuit is independent of the utility grid, power can be supplied at variable frequencies to motor loads with significant positive impacts in load efficiency. Power increases required by the load(s) that occur rapidly can utilize the electrical grid to assist for the brief transient, allowing the engine, which is maintained at a fixed and wide-open-throttle position, to continue operation and in a more gradual process to resume its blend target for power generation.
