This allows the gate to regain control in order to turn the device on at some controllable time after it has again entered the forwardblockingstate.
这样,当晶闸管重新处于正向阻断状态(器件处于可控时间),使得门极变得可控。

During t1 a reverse voltage must be maintained across the thruster and only after this time is the device capable of blocking a forward voltage without going into its on-state.
