UCC28C45-Q1: Convergence problem in TINA

Jash Kothari

Part Number: UCC28C45-Q1
Other Parts Discussed in Thread: TINA-TI

I am trying to make an active clamp forward for a 75v-135v dc input and 12v/20A output using a ucc28c45-q1 grade controller.

When i try simulating the circuit on TINA-TI, i get an error stating that there is a convergence problem, Could someone help me go about?

I have uploaded the TINA File below.

Hi Jash,

Please use below setup for simulation.

But i have not put any initial DC conditions in the input and output capacitance, so do i need to do it?
