The main principle we use this project to reduce the voltage from ac line 220v to 12v dc 12 volts filtered power supply in figure 1 the ac 220v 50hz is connected to the circuit through s1 on off switch and f1 fuse to protect this circuit.

220v to 12v dc power supply circuit.

12v dc regulated voltage supply full wave bridge rectifier. 12v dc power supply schematics. Then they flow through a 2a transformer to reduce voltage into 12v ac. They works well and protected by regulated voltage supply.

First power supply circuit is built with bd139 one zener diode and a few passive components. There are three step. 230v 220v ac to 12 v dc regulated power circuit diagram and 220v 230 ac to 5v dc regulated power circuit diagram using voltage regulator. Firstly 220v ac is converted into 12v ac by using simple step down 220v 12v transformer.

All electronics devices are operated using dc power supply. 220v to 12v dc converter circuit diagram here four general purpose rectifier diode 1n4007 is used to rectify the ac input. The objective of this project is to convert 220v ac supply in to 12v and 12v dc supply that is why it is named dual power supply as we get positive and negative 12v power supply at the same time.
