Abstract :
The Volterra series method is used to predict the spectral components of DC-DC quasi-resonant power converter output waveforms. Volterra kernels computed for the quasi-resonant power converters are based on their small-signal nonlinear model. Illustrative analytical and simulation results are presented for several quasi-resonant power converter topologies and are shown to match very closely
