Symmetry and Duality in ZCS and ZVS Quasi-Resonant Buck, Boost, and Buck–Boost DC–DC Converters
EnergiesQuasi-resonant (QR) DC–DC converters with PWM control achieve soft switching by shaping the commutation transient through a local resonant process. This paper proposes a symmetry-based unified perspective on classical QR converters by interpreting zero ...

Indexing terms: Circuit theory and design, Switching and [PDF]
, 2008 A simple, topology-independent method is proposed for simulating the responses of open and closed-loop quasiresonant DC-DC convertors operating in the zero-currentswitching mode (ZCS-QRC). The method hinges on the substitution of the resonant network and
