How to give a gate pulse to a Mosfet switch depending on voltage and current of different branches using Resonant Converter logic in Simscape Power system?

I want to give a gate pulse to the mosfet depending on the current and voltage of 2 different branches and switching needs to be done. I have current used a matlab function block and written a .m code logic for the switching, but i think i am lagging behind in the initial switching. Please help me out to give a solution.
