Abstract

An electronic component is switched under the control of a pulse-width modulation signal. The electronic component outputs an output signal that is controlled by a control signal. The switching on or off is initiated within a pulse-width modulation cycle period at a level change time by a change of the pulse-width modulation signal. The control signal is set within each PWM cycle period to a first control value between the level change time and a first switching time, to a second control value between the first switching time and a second switching time, and to a third control value from the second switching time until a final gate-voltage value is reached on the gate of the electronic component. Each switching time of a PWM period is determined in dependence on an amplitude value determined during a preceding PWM cycle period, to limit amplitudes of the oscillation of the output signal.
