Hi.
I would like to find out if someone here do or did any ATX PSU conversions for variable voltage & current control. It would be really nice to have a fairly large variable option. 1V - 25V+ but since I work on car stuff and laptops mainly anything from 12V to 20V would be nice.
Current @ 19V atleast 5A | 9A would be really nice for those big gaming laptops. But the main thing would be to have a variable Bench PSU that I could use mainly for testing so that means short bursts 1min - 5mins max esp on heavy load... Other things would include injecting voltages into boards for testing... These would be low current mainly.
I have a Aero Cool Zerodba 500W ATX Modular PSU just laying here. I want to either convert it or strip its parts and build my own PSU from the ground up using the parts gathered from the many parts I have here. I have been busy on and off designing my PSU in Kicad but its a slow process. Just too busy... I have various components some are really high rated ones esp for the switches. Also have various High Freq Transformers.... Whatever I need I can buy.
Chip Details:
- TL3842P
- LM339N
- NCP1653
Attached are photos regarding the PSU in question.
Building it from the ground up is also possible I have all the tools/parts and things needed its really just time... I can get PCB's made professionally from a local manufacturer. So it won't be ghetto shit. I figure once I have the schematic/ Design done I'd post here sometime to get some feedback on it but until then converting/modding the ATX would be preferred.
