However, I came across these error:
Could anyone tell me how to solve this? Thanks in advance.

Can you check setting the priority of parameter from any block to low going to its variable tab.

you need to add an electrical reference to the output of this converter the way it works. (or short the output and input negative termals, or connect them with a large resistance to emulate isolation)

Hi, I was facing a similar issue. Can you please try with local solver. open the f(x)=0 block and there you will see an option for local solver. check that box. Also, try with different solver options. Hope this helps.
