摘要
The switching action in quasi-resonant and pulsewidth-modulated (PWM) converters is attributed to a nonlinear three-terminal switching device for which simple circuit models are obtained. These equivalent circuit models render the dc and small-signal analyses of a large class of PWM and quasi-resonant converters analogous to transistor circuit analysis whereby the transistor is replaced by its equivalent circuit model.
