<P>PROBLEM TO BE SOLVED: To provide a circuit system and a control method for outputting a reverse phase current from a three-phase power conversion apparatus which includes three clusters comprising a series body of one or more unit cells. <P>SOLUTION: In the power conversion apparatus, a delta connection cascade multilevel converter (CMC) which is configured by delta-connecting series bodies of a cluster and a reactor, which are series bodies of one or more unit cells, is linked to a power system. The power conversion apparatus has a function for generally canceling a positive phase reactive current and a reverse phase current caused by other unbalanced load linked to the power system, by concurrently outputting the positive phase reactive current and the reverse phase current from the power conversion apparatus. <P>COPYRIGHT: (C)2012,JPO&INPIT |
