I make the rwilsford07 boost converter, but it doesnt work. The mosfet start heating and only gives 2v. I check the oscilator and is working perfectly, I try diferent things butit doesnt work. Before I make 120v, but I dont know how it stop working, I nad rebuild the circuit like three times but nothing happens. Can you help know why is this happen?

Your inductor is probably faulty, and its saturating, causing the current in the Mosfet to exceed its limit.

I dont think so, before it worked, but now it isnt. I think that is the gate of the mosfet, but I have it exactly as the rwilsford07 boost converter

It might well have worked for a bit. If the Mosfets dead, try another, but observe the primary current
