Abstract
A SEPIC type voltage converter () comprises a transformer () having a primary winding () and a storage capacitor () connected in series, and a controllable switch () coupled in parallel with said series combination. The transformer has a first secondary winding () and a first rectifying diode () connected in series, and a first capacitor () coupled in parallel with said series combination, one terminal of said first capacitor () being coupled to an output terminal (). The voltage converter also comprises feedback means () coupled to said output terminal () and controlling said controllable switch (). The transformer further has a second secondary winding () and a second rectifying diode () connected in series, wherein this series combination is also coupled to said output terminal () in order to limit the voltage across the storage capacitor.
