Problem with "initial conditions failed to converge" when connecting rotational to translational system
Your code looks good. I think that the issue is that it often (depending on how it is connected) lead to index-2 DAE. The eq...

I need to detect the zero voltage for switching on the mosfet .i am currently working on quasi resonant converter.do anyone have an idea on how to detect the zero voltage crossing using simulink blocks?
