Method for synchronous command or regulation of a circuit unit with pulse-width modulated signals and command or regulation unit therefor

摘要

The control circuit includes an interrupt controlled microcontroller (1) sending a PWM (Pulse Width Modulation) signal (PWM) through a wire (4) to an end-stage (2). This produces a voltage signal (U MESS) which is fed back (AD) to the microcontroller. An inductive load (3) is connected to the end stage. The microcontroller may have an output fed back directly to the input.
