A large-signal nonlinear model for zero-current-switch quasi-resonant buck converters is presented. The derivation is simple and the results are accurate even for large-signal operation. Such a model can be used for the analysis and simulation of the switching converter, no matter in open-loop or in closed-loop, with fast speed. The condition for zero-current switching can also be identified from this model.
