Classification: CPC H | IPC H

Claim 5:
6. The control apparatus for a power conversion apparatus according to claim 5, further comprising:
a first average-current calculating unit that calculates a zero-up-side average current that is an average value of the alternating-current current that is acquired during a predetermined period that includes a timing at which the actual voltage is determined to have switched from a negative polarity to a positive polarity by the polarity determining unit; and
a second average-current calculating unit that calculates a zero-down-side average current that is an average value of the alternating-current current that is acquired during a predetermined period that includes a timing at which the actual voltage is determined to have switched from a positive polarity to a negative polarity by the polarity determining unit, wherein
the polarity determining unit corrects the first determination value based on the calculated zero-up-side average current and corrects the second determination value based on the calculated zero-down-side average current.
