Hello
I start using Simetrix / Simplis and try to adapt my models from Spice programs. I have a problem with simulating a compensator with optocoupler.Only when I try to repeat compensator with optocoupler. Without optocoupler I have the same results with Spice programm (LTSpice, PSpice). Please give me advice, I want to understand what I'm doing wrong. Please look on pictures: 1 – it is scheme, 2 – results that I have, 3 – results from Spice. 3 is correct. How can I get the correct answer (graphics) using Simetrix / Simplis.
