Abstract
An example of the current source power conversion circuit is provided with a plurality of half-bridge rectifier circuits which are connected in parallel, each including a serial connection of a first switch circuit having a first self-turn-off element and a first diode which are connected in series to each other, and a second switch circuit having a second self-turn-off element and a second diode which are connected in series to each other. A first current electrode of said first self-turn-off element in one of said half-bridge rectifier circuits and a first current electrode of said first self-turn-off element in other one of said half-bridge rectifier circuits are short-circuited and connected.
