Circuit diagram Power Supply with good stabilization.

The power supply should be capable of supplying the maximum current required with good stabilization. I used commercially available 40 – 0 – 40 5A transformer. The transformer have 6V, 9V, 12V and 22V windings also. The transformer cost me around Rs: 370. Power supply provides 110 Volt 2.5 Amps or 55 Volt 5 Amps. […]
