UCC28070: UCC28070 PSIM

Tool/software:

Hi, 

I want to simulate interleaved boost pfc on the PSIM with the UCC28070, but I can't get any boost. The input voltage is transferred to the output as is. PWM is always 0. What should I do? I'm attaching the file. I can get correct results in the TINA TI application with the same values.
