1. Method of controlling a switch, said method comprising steps of:
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, the switch switching to an off state within a turn-off time from the first switching; and
b) applying a switch turn-off potential to said control terminal after a first delay starting at said first switching, the first delay being longer than the turn-off time, wherein:
the first switching marks a beginning of a first period during which said control signal is only in the turn-off control state;
a second period comprises alternations of states of control of the turning off and the turning on of the switch;
the first delay is longer than a cycle time of the alternations;
said control signal exhibits, during said application of the turn-off potential, at least one second switching between the turn-off control state and the turn-on control state; and
said application of the turn-off potential is interrupted within a second delay starting at said second switching and shorter than the first delay.
