By using the diode in series with the GTO, the switch significantly increases the turn-off voltage that can be used for the current commutation. The unity turn-off gain and the snubberless turn-off capability are demonstrated.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/66/266/064/0.pdf9708505327/438327/440H03K17/0403H03K17/7326426666
