Abstract

The forward converter with clamp is nowadays one of the most useful topologies when low output voltage is required due to the possibility of using self driven synchronous rectification. This paper shows a study of the peak current mode control when the main MOSFET current is sensed instead of the current passing through the output inductor. A dynamic study is accomplished and the control problems are shown. Finally, several practical ways to close the feedback loop avoiding the dynamic drawbacks is also presented
