Hi, I'm a bit baffled by those switching mode power supplies found in computers, why need they be so complicated? As I understand it, high frequency + transformer= higher current handling capability, smaller transformer. But then, can't I just rectify the mains voltage, send it through a MOSFET driven by a 555 or something, and send that into the transformer?
Yes, I understand a good deal of the circuitry is to provide other voltages and safety. But still...
Also, what makes a high frequency transformer a high frequency transformer? (Core, windings, what?)
