I need some help on make a small signal model of the power stage of forward or flyback converter. I have some experience in modeling the power stage of buck/boost power stage from the papers of Ridley or Vorperian. But I am got by the transformer in Forward/Flyback converter。 Any suggestion or material is welcome.
thanks all. I have already solve the question. the transformer does not influence the main pole of th flyback/forward than the boost/buck converter. the flyback likes
buck-boost, the forward like the buck.
