Abstract
A system and method of harmonic regulation includes a harmonic regulator configured to cancel or inject harmonics into a power conversion system. A resettable integrator is provided to determine at least one harmonic coefficient of the at least one error signal harmonic. The resettable integrator determines the at least one harmonic coefficient over a single signal period and is then reset. The harmonic regulator further includes at least one adder to determine a difference of the harmonic coefficient and the reference harmonic coefficient and a regulator is provided to determine an at least one axis harmonic reference signal. The harmonic regulator outputs a three-phase final electrical reference signal that is input into a DC/AC inverter of a power conversion system.
