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 1):
A bidirectional chopper circuit that bi-directionally performs voltage conversion between a first DC voltage across a pair of first external connection terminals and a second DC voltage across a pair of second external connection terminals, comprising:\n a main power converter including a first switching unit and a second switching unit, which are connected in series with each other so that conduction directions in an ON state are aligned and one of which is turned OFF when the other is turned ON, the main power converter having, as the first external connection terminals, both terminals on a side opposite to a side on which the first switching unit and the second switching unit are connected; one or a plurality of single-phase full-bridge power converters cascaded with each other provided on a wiring line that branches from a wiring line connecting the first switching unit and the second switching unit; and an inductor connected in series with the single-phase full-bridge power converter on the wiring line that branches from the wiring line connecting the first switching unit and the second switching unit, wherein, at any position on the wiring line that branches from the wiring line connecting the first switching unit and the second switching unit and is provided with the inductor and the single-phase full-bridge power converter, the pair of second external connection terminals and are provided.
