I'm new here, and I'm new to electronics. I have a keen interest in building a wind powered battery charger and I'm having a crack at the charge controller. I found a circuit that is published free on the 'net and after a few false starts and blind alleys I finally finished my charge controller- or so I thought! My mosfet exploded (well,it went pop and split apart really but it surprised me).
Can anyone tell me what I might have done wrong? Will it have damaged any other components on the board?
If it helps, its an IRF9520 P channel mosfet. I'm not sure whether it should have been an N channel - would this have caused the problem?
Grateful for any help or advice.
