Hello,

I'm trying to design SMPS with PFC function using Boost Converter in PSpice. I have a problem with pwm signal. Depending on the value of voltage of triangular signal (Vref_PWM1), the results changes. I need help to choose right value of this signal and PI controller values. Are there other simple ways to generate a PWM signal?

hi K,
I don't use Spice, but many other members do, by posting your simulation file it should help with replies.
I use LTSpice.

Maybe, I didn't understand you correctly or I'm doing something wrong, but I've attached .sch simulation file. I don't use LTSpice.
