Abstract: A method for enhancing the operation of an electrical power supply includes selecting a prime mover having a chosen power rating. An induction motor having a first power rating at a rated speed and a second power rating at an overspeed is chosen. The overspeed may be at least about 10%, or at least about 25%, 50%, 75%, 10 to 300%, 25 to 300%, or 50 to 100%, greater than the rated speed. The induction motor may be chosen so that the second power rating is substantially the same as the chosen power rating of the prime mover. The induction motor is driven by the prime mover so that the induction motor acts as an induction generator. The system may also comprise a control module to monitor the performance of the power supply and to provide a throttle control signal in response to a control parameter signal. A circuit input of a phase shift circuit may be connected to a generator output. A converter input of an AC to DC converter may be connected to a circuit output of the phase shift circuit.
