| Abstract |
This paper presents the high frequency behaviour of Quasi-Resonant Switch Mode Power Supplies. First, the two modules of commutation (zero-current-switching and Zero-Voltage-Switching) are studied and compared on an elementary commutation cell using MOSFET technology. These results are compared with simulation taking into account switching transitions. The next stage refers to passive components (transformers inductors and capacitors). Three different transformers have been built and the losses have been measured with a calorimeter for several switching frequencies. These results will help the choice of frequency for quasi resonant converter. |
