Abstract:
A bidirectional chopper circuit  1  is provided with: a main power converter  11  having a first switch  21 - 1  and a second switch  21 - 2  set up so that one switch is turned off when the other switch is turned on and connected in series with each other so as to line up in a conduction direction when turned on, the terminals on both sides of the main power converter  11  on the opposite sides to the connection sides for the first switch  21 - 1  and the second switch  21 - 2  being a pair of first external connection terminals; a plurality of single-phase full-bridge power converters  22 - j  and a pair of second external connection terminals provided on wiring that branches from wiring connecting the first switch  21 - 1  and the second switch  21 - 2  so that one or both are connected in cascade; and an inductor  13  connected in series with the single-phase full-bridge power converters  22 - j  on wiring that branches from wiring connecting the first switch  21 - 1  and the second switch  21 - 2.

Claim (Index 3):
The bidirectional chopper circuit according to  claim 2 , comprising:\n a control unit for the main power converter configured to control duty ratios of the first switching unit and the second switching unit in the main power converter so that a current flowing through the inductor follows a predetermined command value; and a control unit for the single-phase full-bridge power converter configured to control a power conversion operation of the single-phase full-bridge power converter so that an AC voltage for canceling an AC voltage component of a voltage appearing at a connecting point of the first switching unit and the second switching unit in the main power converter is output while a DC voltage of the DC capacitor is held at a predetermined voltage.
