TINA/Spice/UCC28070: UCC28070 simulation example doesn't work with OrCAD 16.6

Hello,

I simulated both  "transient model"  and "average model" downloaded from web  in PSPICE  16.2 and 17.2 versions and it worked in both. I do not have 16.6 and I am not a fan of using it. 

I suggest you give it another try in one of these versions and see if  it works for you, just make sure you test it  without any modification to the test bench  first. 

Regards,

Hi, Arash:

Can you show us simulation result.

We tried both PSpice transient model and Tina transient model but the result are same. It seems that UCC28070 is not starting to regulate PFC output.

Yanbin,

PSpice result in 16.6:

Hi, Britt:

I think VOUT waveform is OK but IVIN waveform is NOK. The THD is poor. Current wave is not a sinusoidal wave.
