Claim 0:
1. A control system of a power converter comprising:
a plurality of carrier wave generating units respectively provided for a plurality of power converters connected between a plurality of DC power supplies and a common AC power supply, the plurality of carrier wave generating units being configured to respectively generate carrier waves on a basis of an AC voltage of the AC power supply; and
a plurality of current control phase generating units respectively provided for the plurality of power converters connected between the plurality of DC power supplies and the common AC power supply, the plurality of current control phase generating units being configured to respectively generate AC voltage phases for current control respectively for the plurality of power converters on a basis of the AC voltage of the AC power supply,
wherein the plurality of current control phase generating units respectively generate AC voltage phases for current control respectively for the plurality of power converters after applying filters to the AC voltage of the AC power supply, and
the plurality of carrier wave generating units respectively generate AC voltage phases for carriers respectively for the plurality of power converters after applying filters slower than the filters of the plurality of current control phase generating units, to the AC voltage of the AC power supply.
