Abstract
A zero voltage switched power supply converter includes a series combination of a first winding and a first switching element. A second winding is connected to a second switching element and to a storage capacitor, and a series combination of a second storage capacitor and a third switching element is connected in parallel with said second switching element, so that when the second switching element becomes non-conducting, the third switching element continues in the conduction state, starting a first resonance period that concludes when the third switching element becomes non-conducting and starts a second free resonance period, and the switching is achieved at zero voltage.
