I am doing some work trying to derive the transfer function of a resonant LCC power supply. I have come across analysis online which shows the derivation of the input impedance of the converter, which I have attached.
My question is a basic one which may sound stupid, but i've not much experience in this part of the design procedure yet. The impedance equation looks a lot like a typical transfer function with some laplace terms. But, is it the same? If not, how would the transfer function be extracted so that I can design a PID controller or some sort to close the feedback loop?
