UCC256402: HALF BRIDGE LLC DESIGN CLOSED LOOP SIMULATION

Alper Çimendağ

Part Number: UCC256402

Hello,

I am trying to do LTspice simulation of half bridge LLC converter. However, I cannot find simulation models LLC controllers such as UCC25640X. If there is no SPICE model for this controller, how do I close my feedback? Any recommendation?

Thanks,

Alper

Hi Alper,

We do not have any spice models for this controller. We do have Simplis models.

For closing the feedback, you need to implement the hybrid hysteric control using logical blocks.

Or If you just want to steady the LLC closed loop, you can implement the spice model in voltage mode control by referring the following app note.

Please see the page 11 of this app note: Design Guide Evaluation board EVAL_600W_12V_LLC_P7
