I just need help understanding it (no project, no nothing in mind to do just been nagging away at the back of my mind)
Is this understanding correct? a PSU from 110vac 50hz, the PWM side could simply compare the voltage and if it's between 0 - 15v the PWM allows the electric/current to pass through to the caps and then onto the regulators and so on eventually feeding the components.
If it is, how exactly would PWM work if you're using say 8 - 12vdc but you want to feed something that connects to 3volts.... since there's no sinewave it's going to be a constant 8-12vds...
So how does it supply the 3.2volts (could be any voltage but argument sake 3.2v) from 8v or higher?... ?? this is driving me insane i find lots and lots of information about Switching Power Supplies/PWM using 110/240acv but nothing about 8-12v DC stepping down voltage?.... (only thing i can think of is it it converts it to AC and goes through a transformer)....
Anyone want to put my understanding right so i can stop thinking about it lol it's driving me insane.
