Abstract :
In this paper, aspects of the real operation of a single-cycle quasi-resonant power converter are analyzed and experimentally verified. In particular, electrical stresses and power losses in the complementary power switches are considered. A variable timing strategy of the switches, based on the direct measurement of the resonance period, is proposed and described. The experimental results and comparisons carried out on a laboratory prototype of the power converter are reported and discussed
