Abstract

A power conversion system includes an inverter circuit, a harmonic reducer, and a synchronizer. The inverter circuit is operable with electric power supplied from an alternating-current power source. The harmonic reducer is connected to the alternating-current power source. The inverter circuit includes a circuit main portion and a conversion control unit configured to control the circuit main portion. The harmonic reducer includes a current control unit configured to perform control to reduce a harmonic current flowing to the alternating-current power source. The synchronizer is configured to synchronize a state of the harmonic reducer with a state of the inverter circuit.
