Two Examples Are Quasi Resonant Flyback And Pfc, Where The Mosfet Is Turned On During The Parasitic Resonance That Follows The Inductor Current Hitting Zero.

The performance of the converter is improved by introducing pid controller and fuzzy logic controller. Frequency is lower than resonant frequency, the converter will work under zero current switching (zcs) condition. In theory, the on off transitions occur at a time in the resonant cycle where the switch current is zero, facilitating zero current, hence zero power switching.
