Hello, i was intending to buy some power supply units from ebay to use on my future projects, but i thought, i could use this as an opportunity to learn how to make them, but i'm afraid this is not a trivial task, an psu that uses the smps technique seens rather complex to even try to do.
So first i went to see if i could find some ready to use modules, and i found some:
85-265 AC to DC 12V 8A
5V 1A AC TO DC
12V 1A AC TO DC
They seen to be really good, taking a quick look, the boards have emi filters, fuses, thermistors... but i don't know if they can really deliver all this current.
Even if they could not deliver this amperage, they seen to be really awesome and for this price a time saver.. is just a board ready to use(awesome!)
So i did not found any negative points for buying.. but for building there is a lot of negative poinst rsrs. Just to start with:
1) I don't know where to find these transformers.
2) To make a really good smps psu requires a deep knowledge of inductors, capacitors and ic's..
So what i should do? Go for the obvious that is buying, or embark on a wonderfull journey through the lands of power supply units?
