The project I want to build is shown below. I want to operate the P-channel mosfet on and off with variable frequency from 20-100Hz and I choose P-channel to do this so that the +350V will not be present on the load when the control circuit is off.
I want also the high power supply to the mosfet and the load to be separated from the control circuit.
My questions are:
- Will this circuit works? please give me suggestions or revisions.
- What if the load is disconnected or fails and becomes "open circuited" - will be high voltage present on the drain or will the mosfet still switch on and off in that case?
I am new to electronics.
