Abstract: A converter system includes a first switch, a first sensing unit configured to generate a first sensed signal proportional to a current through the first switch, a second sensing unit (118) configured to generate a second sensed signal based on a difference between a reference voltage and a feedback voltage, a DC compensation unit configured to generate a slope peak DC signal relative to a slope peak of a slope compensation signal, and a signal combination unit configured to generate a control signal based on the first and second sensed signals, the slope compensation signal and the slope peak DC signal to switch off the first switch.
