Boost Converter with a PI Controller (closed-loop system) in PSPICE

[mothermohammad]

Hi,

I designed a Controller for a Boost converter. I simulated it in PSIM and I get good result. However, I have problem in PSPICE.
I don,t know how should put the Opamp in the PSPICE. I saw a circuit in the book of "Hart" that, he used ETABLE as omapm and PWM Comparator. Still, I could not get any solution. I am thankful if you help me.
I used the block of "Comp" for comparing rawtooth with the generated signal. I used ELAPLACE block to insert the transfer function of controller.

hello mohammed, i dont see any PI in ur design, i am just here for knowing

The OP told where the PI function is

I used ELAPLACE block to insert the transfer function of controller.
