Abstract
A power conversion scheme for transferring power between a DC current source and an AC voltage source employs a polyphase bridge and a thyristor to short circuit the DC current source to interrupt AC current. Comutation of the thyristor is achieved by scheduling firing switch devices of the bridge as a function of phase voltages of the AC voltage source.
