Abstract
A power system is presented. The power system includes a first converter including a first output terminal a first control unit coupled to the first converter, a second converter including a second output terminal, where the second converter is coupled in parallel to the first converter, and a second control unit coupled to the second converter. The second control unit is configured to measure a plurality of phase currents at the second output terminal, determine a harmonic current transmitted by the second converter based on single phase current of the plurality of measured phase currents, and change a time-period of at least one switching cycle of a carrier wave of the second converter based on the determined harmonic current to synchronize with a carrier wave of the first converter.
