I need a simple ups circuit for desktop computer.
I need a simple easy to construct ups circuit for desktop computer. By now I have searched various websites but till now not succeeded to find the suitable ups circuit for desktop. What I need is that the circuit should be easy to assemble and I do not want microcontroller based circuit. It should be of 625 VA. I will be very thankful if somebody suggests me a reliable website from which I can get this circuit.
