Abstract
A converter includes a time-delay circuit for a PWM signal, applied to input of the time-delay circuit, by which rising edges of the PWM signal are delayed by an ON delay and falling edges of the PWM signal are delayed by an OFF delay, in order to form a drive signal, available at the output of the time-delay circuit, for a semiconductor switch element. The time-delay circuit includes two resistors, two capacitors, a diode and a comparator, and is therefore particularly easy to implement.
