摘要: A PWM switch large signal model for a flyback converter having arbitrary transformer polarity is presented. This will preserve the input-output property regardless of polarity. small novel one-stage, switched-mode power factor correction (PFC) also presented in this paper. The obtained by applying perturbation technique to circuit equations derived from state-space averaging method. It shown that exhibits characteristics second order low-pass system output-to-input transfer function, and combined band-pass output-to-control function. validity mathematical was verified given experimental results.
