A current source power conversion circuit uses a reduced number of driving power supplies and has an inexpensive and simple configuration. The current source power conversion circuit is provided with a plurality of half-bridge rectifier circuits (2r, 2s, 2t) which are connected in parallel, each comprising a first switch circuit comprising a first self-arc-extinguishing element (3r, 3s, 3t) and a first diode (4r, 4s, 4t) which are connected in series with each other, and a second switch circuit comprising a second self-arc-extinguishing element (5r, 5s, 5t) and a second diode (6r, 6s, 6t) which are connected in series with each other, the first switch circuit and the second switch circuit being connected in series. A first current electrode of the first self-arc-extinguishing element (3r, 3s, 3t) of one half-bridge rectifier circuit (2r, 2s, 2t) and a first current electrode of the first self-arc-extinguishing element (3r, 3s, 3t) of the other half-bridge rectifier circuit (2r, 2s, 2t) are short-circuited and connected. |
