Abstract
In a method for generating a PWM-signal to drive the power transistors of a half-bridge of a converter with the aid of a digital circuit, a digital reference value is compared to the counter content of a digital counting ramp, and a logic state of the PWM-signal is dependent upon whether the reference value is greater than the counter content of the counting ramp. In this context, at least two counters count counter contents of the counting ramp following one another in alternation, and the logic state of the PWM-signal is dependent upon whether the reference value is greater than the counter contents of counting ramps of each of the at least two counters.
