Not sure where this belongs... 3-Course Meal doesnt belong in here but that didnt stop me!
I reckon i`m way past the normal meaning of BORED so... i`m gonna look into PSUs. Chances are i`m gonna learn stuff here...and you lot might too Who knows! Not me!!
First of all a PSU converts an AC signal into a DC one.This is done with a rectifier. theres 2 kinds: 1/2 wave and full wave. Diagrams below
1/2 wave or full-wave? Theres a question. BTW...Despite theory at uni, I dont really know as much about this as I maybe should, so this really is a journey of discovery
AC signals from the mains are 60-ish Hz, and switching PSUs switch this 60Hz to a higher number to make it easier for the transformer to switch down to the 3.3, 5 and 12V lines we know. The higher frequency is also easier to rectify apparently, and leaves smaller fluctuations for components to deal with.
3 steps so far: we have to take the 240V mains voltage, switch it to a higher frequency, rectify it, and transform it down to whatever voltage we need.
Switch, transform, rectify.
I guarantee i`ll make mistakes with this, so feel free to point them out...before I hurt myself would be appreciated!
