A hybrid induction machine includes a stator with an input winding, a plurality of output windings with output ports, and a rotor connected to a flywheel operating as a reserve of kinetic energy to buffer surges in demand for electrical power due to large, pulsed loads with high repetition rates. Degradation of power quality at the output ports of the hybrid induction machine due to electrical noise on a main bus providing electrical power to the hybrid induction machine and other apparatus can be eliminated through the use of feed-forward harmonic cancellation signals, galvanic and magnetic isolation of the output ports, and damper networks.
