Abstract:
A method for outputting an analog value at a PWM output of a driver for a power semiconductor. The method comprises converting the analog value to a PWM signal which has two signal levels and which is at a fixed PWM frequency. For an inactive state of a binary supplementary value the PWM signal is output at the PWM output. For an active value of the supplementary value the PWM signal is output together with a supplementary signal at the PWM output. The current signal level of the PWM signal and the respective other signal level are output alternately as a supplementary signal at a signal frequency greater than the PWM frequency.
