Abstract
Systems and methods for supplying power to a load include a static switch between a primary power source and a power conditioner associated with a secondary power source, and maintenance switches between the primary and secondary power sources and a load. A controller is operable to actuate the switches. The static switch is operable to conduct power from the primary power source to a capacitor associated with the power conditioner. Current supplied from the primary power source includes portions at a fundamental frequency and a harmonic frequency. The secondary power source or the capacitor, or both, can be used to supply reactive power having a current equal and opposite that of the harmonic portion such that substantially all of the current provided to the load by the primary power source is at the fundamental frequency.
