Abstract:
This chopper circuit 1 performs voltage conversion between a first DC voltage at a first external connection terminal and a second DC voltage at a second external connection terminal and is provided with: a first switch portion 11 having the first external connection terminal; a second switch portion 12 connected in series with the first switch portion 11 so that the conducting direction during ON-time matches that of the first switch portion 11 and having the second external connection terminal on the opposite side to the side where the first switch portion 11 is connected; one or a plurality of semiconductor power converters 13 cascade-connected to each other, which are provided on a wire branched from the wire for connecting the first switch portion 11 and the second switch portion 12; and an inductor 14 connected in series with the semiconductor power converters 13 on the wire branched from the wire for connecting the first switch portion 11 and the second switch portion 12.
