Novel high frequency quasi-resonant converter topologies

Abstract

The concept of Nth order quasi-resonant switching cell (QRSC) is introduced and the synthetic technique of Nth order quasi-resonant converters (QRCs) is developed. Using this technique, the authors synthesize 2nd-4th order buck QRCs. 4th order ZVS-QRSC is taken an example to demonstrate how to get corresponding 4th order ZVS-QRC topologies.<>
