Dear sir,
I want to stimulate SMPS circuit on LtSpice and TINA TI but facing some issues.
1. On LTSpice, the IC UCC28C40 is not working even after providing the biasing voltage. I have enclosed the same.
2. On Tina TI the stimulation results are very different from the desired outcome i.e., the aux will not able to generate any voltage. I have enclosed the same.
Not only this if I remove the aux and use only primary and secondary winding only the circuit is operating partially.
Hi,
I created a new circuit based on your circuit and a workable circuit. Attached. It works normal. You can modify the attached circuit to your need one step at a time to find which step the circuit shows not working. Then find out why.
