PROBLEM TO BE SOLVED: To provide a power converter capable of improving the conversion efficiency of the power converter to supply the power to a load while ensuring harmonic suppression function.SOLUTION: A controller outputs a pulse signal to a first switch and a second switch based on a circuit current flowing on a power conversion circuit and a voltage of an AC power. The first switch opens and closes alternately with the second switch. With this open/close operation, a current in which a low frequency component and a high frequency component of the AC power are mixed flows on the power conversion circuit. |
