Here are the gain and phase plots of a flyback SMPS.
Do they look allright?
The actual flyback runs off rectified mains which fluctuated between 150V and 330V at 100Hz.
I had to pick a single Vin for the bode plots, so I picked 150V.
Schem, LTspice sim and bode plots attached
vout = 30v, pout = 22.5w, fsw=97khz, cout = 470uF, current mode, CCM, continuos mode,
