LTSpice Buck Ideal PI Control Kp Ki Tuning

Thank you very much sir. I learned a lot from your videos and it is helping me with my thesis work. I was wondering if I can get any help from you on my work. I'm working about totempole PFC. I am having trouble with the control signal for the mosfet's gate pulse.

Thank you for watching my video If you are working with PFC, your configuration Will probably be a boost converter, with Low side switch That MOSFET, should switch following the 100Hz rectified pulsed line voltage that you have at the input. Basically, you Will have two ripple in your circuit: the FSw ripple at your switching frequency, like 100kHz and the 100Hz Now, for the control, you Will probably have to design a type2 compensator, because boost converter have the inductor on the input side and they don't need type 3 , in both cases of voltage and current control. Remember that type2 control Is basically a PI control Anyway, I intend to make more videos about PFC in the near future, so stay tuned
