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 8):
The power conversion apparatus according to  claim 6 , wherein the bidirectional conversion circuit comprises\n a first series circuit that includes a first switching element and a second switching element connected in series, a second series circuit that includes a third switching element and a fourth switching element connected in series and that is connected to the first series circuit in parallel, and a diode connected in antiparallel to each switching element, wherein the control unit performs control so as to repeatedly switch between a state where the first switching element and the fourth switch element are turned on and a state where the fourth switching element is turned on, during the former stage of each positive half cycle of AC voltage, and to repeatedly switch between a state where the second switching element and the third switching element are turned on and a state where the second switching element is turned on, during the former stage of each negative half cycle of AC voltage, and the control unit further performs control so as to repeat a state where the second switching element is turned on during the latter stage of each positive half cycle of AC voltage and to repeat a state where the fourth switching element is turned on during the latter stage of each negative half cycle of AC voltage.
