查询词典 turn-on

For confirming the method's efficiency, the turn-off transient mathematical model based on the chopper circuit is developed according to the proposed mathematic model of the turn-off transient current through IGCT, in which the RC-snubbers of IGCT, the stray inductance of chopper circuit and DC-link choke are taken into accounts.
