Pratishwar Bhartiya54

Part Number: UC3854
Other Parts Discussed in Thread: TINA-TI, ,

Tool/software: TINA-TI or Spice Models

I am trying to simulate PFC boost section using PWMBST model of boost converter in closed loop with UC3854_SAC library model available in Pspice. I could able to use PWMBST in open loop but not getting the result when I am using UC3854_SAC to simulate in closed loop.

I would appreciate if you could give me your suggestion and let me know if I can use UC3854_SAC with PWMBST model.

Any suggestions & advice will be greatly appreciated.

Hi Pratishwar,

I am unaware of the SAC library in PSpice. If this is something that Cadence has developed, you can post a question on the PSpice community page: www.pspice.com/pspice-sac-models-doc.

If you have specific questions about the device, then the following TI E2E forum would be a good place to ask those questions.

Hi Pratishwar,

Unfortunately, we do not have a model for this device (PSspice or TINA-TI). That is why I recommended in my original post that you can direct any device related questions to the forum for isolated AC/DC devices.
