Hello Nicklas, I have the open loop frequency response of 1/2 bridge inverter capacitor current (using PSIM). Now I would like to convert that response into a transfer function so that I can create the closed loop response (as you mentioned). I do have an exact transfer equation for the capacitor voltage with respect to duty cycle so maybe that can somehow be changed to capacitor current since capacitor current equals C*dv/dt. Maybe just multiplying by Cs would do it?
