Does anyone experience after replacing a v-switch with mosfet in the full-bridge, then the circuit doesnt work as normal. And the circuit is shown as below. I wanna ask if there is any gate drive circuit need to be added or what's going on?
Thanks for help

The upper two fets in the H bridge require a gate voltage higher then V3 can deliver to become activated. I can't see if this is the case or not as i don't really understand what COMPHYS is.
