Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. Sgs thomson s ic lm338 in conjunction with a very few passive components is able to produce voltages right from 1 2 to 32 volts. The final project i wanted to build was a wall adapter with a usb socket to charge my iphone. Converting 220v ac into 12v ac using step down transformer.

12v 1a linear regulator using transistor and zener diode. If you are planning to build a 0 to 12 volt dc power supply unit for your work bench this article may specifically help you. 0 28v 6 8a power supply circuit diagram using lm317 and 2n3055 this design can produce a current of 20 amps with little modification use proper rating transformer and a huge heat sink with fan. Huge heat sink is required in this circuit as 2n3055 transistors produce large amount of heat at full load.

It is actually very similar to most of the lm317 based power supply with some key difference. It is a charge pump circuit used to create a low power negative dc voltage source. A lot of 6v supply. The primary terminals of the centre tapped transformer is connected with household supply 220v ac 50hz and output is taken from secondary terminals of the transformer.
