Abstract:
    The invention relates to a buck/boost bidirectional alterative-current chopper, which comprises power circuit formed by capacitor with one end connected to ground and one parallel alterative-current sine voltage power source; the first buck/boost circuit, and the second buck/boost circuit. The invention has the advantages that: the whole circuit has non arm direct connection, to solve current diversion; and it can realize voltage-decrease voltage-increase AC/AC conversion, to bidirectional transmit energy; and it has low circuit consumption with simple control; and it outputs average voltage value or effective loop-close adjustment.
