I would like to build a PWM switch model for the following voltage-fed push-pull converter (which operates in current mode) to determine its transfer function.
I can handle simple topologies like buck and boost, but I don’t know how to rearrange the push-pull circuit for the PWM switch model. There is some information on Ridley's site regarding the forward converter, but unfortunately, I can't figure out how to apply it to the push-pull converter.
