Power losses in MOSFET switch of quasi-resonant pulse converter with series resonant circuit

This article presents the analysis of electromagnetic processes in MOSFET switch of a zero-current switching quasi-resonant pulse converter with series resonant circuit. The analysis performed by stitching equations illustrating change of MOSFET current and MOSFET voltage. The obtained results for each switching interval allowed to estimate the overall power dissipation and power losses for all switching intervals.
