Abstract:
A power conversion apparatus comprises a bidirectional conversion circuit that enables first conversion converting DC to AC and second conversion converting AC to DC and a filter circuit that is provided on an AC side of the bidirectional conversion circuit and that includes a capacitor. A control unit is provided for performing control such that the bidirectional conversion circuit makes the first conversion during the former stage of each half cycle of AC voltage, and performing control such that the bidirectional conversion circuit makes the second conversion during the latter stage of each half cycle of AC voltage. The control unit performs control such that AC current of an opposite polarity to that of the AC voltage flows to an AC side of the bidirectional conversion circuit during the former stage and performs control such that AC current of the same polarity as that of the AC voltage flows to the AC side of the bidirectional conversion circuit during the latter stage.

Claim (Index 9):
A control method for a power conversion apparatus comprising a bidirectional conversion circuit that enables first conversion converting DC to AC and second conversion converting AC to DC and a filter circuit that is provided on an AC side of the bidirectional conversion circuit and includes a capacitor, comprising:\n performing control by a control unit such that the bidirectional conversion circuit makes the first conversion during a former stage of each half cycle of AC voltage, and performing control by the control unit such that the bidirectional conversion circuit makes the second conversion during a latter stage of each half cycle of AC voltage, wherein the control unit performs control such that AC current of a polarity opposite to a polarity of the AC voltage flows to the AC side of the bidirectional conversion circuit during the former stage and performs control such that AC current of a same polarity as a polarity of the AC voltage flows to an AC side of the bidirectional conversion circuit during the latter stage.
