Abstract:
    The invention relates to a bidirectional alternative-current chopper, which comprises the first and second buck (boost) circuit, wherein in the first buck(boost) circuit, the cathode of first switch and the anode of second switch are connected, while the connecting point is connected to one end of first inductance filter; in the second buck(boost) circuit, the anode of third switch is connected to the cathode of fourth switch, while the connecting point is connected to one end of second inductance filter; another end of first inductance filter and another end of second inductance filter are connected to one end of second inductance capacitor; the anode of first switch and the cathode of third switch are connected to one end of first filter capacitor; the cathode of second switch, the anode of fourth switch, another end of first filter capacitor, and another end of second filter capacitor are connected. The invention can avoid control dead area, to solve current diversion.
