摘要： A method of controlling a switch, including: a) applying a control signal to a control terminal of the switch, said control signal exhibiting at least one first switching between a switch turn-on control state and a switch turn-off control state; and b) applying a switch turn-off potential on said control terminal after a first delay starting at said first switching, the first delay being greater than the turn-off time.
