Classification: CPC H  Y | IPC H

Claim 1:
2. The power conversion device according to claim 1, wherein,
in the first operation mode, the control circuit controls on and off of each of the positive-side switching elements and each of the negative-side switching elements of the first and second bridge circuits so that
in one of the first and second bridge circuits that outputs the one of the first AC voltage and the second AC voltage, a second phase difference is provided in an on and off phase in which the on and off of the positive-side switching element and the negative-side switching element is switched, between the plurality of switching legs, and
in the other of the first and second bridge circuits that outputs the other of the first AC voltage and the second AC voltage, the on and off phase is identical between the plurality of switching legs, and

the second phase difference is set in accordance with the length of the zero voltage period.
