This is my first port, after searching on google about how to make UPS.
Because of loadshedding problem, and power tripping, I always face problem with UPS and have to bring it for repairing, which is a hassle all the time.
therefore I want to learn how to make a UPS and its repairing so that I can repair minor problems my self.
So the question is, how can I learn about making and repairing UPS?
I'm from Multan, therefore specially if some one from Multan is available who can teach me this, It would be appreciated.
