A nonlinear model for zero-current-switch quasi-resonant-converters is proposed which can be derived easily using simple analytical techniques. It is readily accepted by MATLAB for analysis and simulation in fast speed. Simulations have shown its accuracy even for large-signal transient dynamics. The condition for zero-current switching is also identified from this model.
