Title: BIDIRECTIONAL CHOPPER CIRCUIT
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.
