Abstract

A controlled drive circuit for an analog controlled power semiconductor includes a digitally operating logic module, which has a control input receiving control signals from an A/D converter and a control output supplying processed control signals to a D/A module that converts the processed digital control signals signal to an analog or quasi-analog control variable that controls the power semiconductor.
