I'm watching a video talking about a basic flyback converter, and he says you don't need an inductor on the output, unlike in a forward converter. In most every ATX SMPS I've seen and taken apart, there are always lots of output inductors spread around the rails.
I know in a flyback converter the current rises in 1 inductor, building a B field in the core, and only after the switch is off, does the current in the secondary side start.
So in a Forward converter, the current flows on both sides when the mosfet is on.
Well what type is in 90% of computer ATX PSU's ? Are they FLY's using output inductors too? Some PCB's label the main "transformer" as FLY
Or are they usually DC-DC forward converter's ?
I have differential probes, so I can probe both sides of 1 of these things and see what the voltage is doing at least, I guess if I looked at the Vf of an output diode I'd know if that side was conducting.
