 		 #79540 - RE: driving power mosfet, gnd potential diff
Responding to: ???'s previous message
Hello Steve,

I think you misunderstood the power supply diagram. The rail of -V is not connected with AC mains. This is isolated from each other.

Yes, you are right that I would need a flywheel diode on the Field winding I will do it. The surity of not turning ON the arm before field is powered, it is accomplished by software.

But my immediate problem is driving the power MOSFET even to drive a 100W light bulb.
