Abstract
A method and a device for control of a switching operation consisting of a turn-on or turn-off operation in a voltage-controlled power transistor (T1), wherein at least one current source (S1, S2) is arranged at the control electrode (G) of the power transistor for controlling the recharging of at least one of the capacitances which occurs between the control electrode (G) of the power transistor and the main electrodes (C, E) of the power transistor and thus to determine the time rate of change of at least one of the quantities voltage and current.
