Hey guys i need some crude but functional psu that can give a 120vdc and about 200 mA of current.
I need this power supply beacose i have 3 led strips that are conected in series.Each one of them uses about 40v and around 50mA,so 3×40 is 120v.
I was thinking about a voltage doubler but i don't know if it is eficient enough.
The second idea i had to mind is to rectify 220 v ac with full bridge rectifier and somo filter capacitor and when the ac is converted i will get around 320 v dc.So i wanted to put a voltage devider beacose i don't need much current.And with that devider to stepdown the voltage to 120v dc .
Please help and guide me i will apreciate it
