A quick learning tutorial about what is a dc power supply. This is the most easiest and simplest 220v to 12v dc power supply.

You can get this project in PDF file as well. A 220v ac to 12v dc power supply project. Like running a 12 volts motor, any circuitry that need 12 volts dc ,a dc fan, charger etc. These DC voltages can be utilized in any dc operated 12 volts AC to DC converter project. The output is not is fixed 12 volts dc voltages. The simple transformer based power supply circuit output is 12 volts fixed DC. The filtered 12 volts DC output is generated.

Now you can connect any DC operated circuitry to 12-VDC output.

The LED shows the rectified filtered output of 12 volts DC.

The use of capacitor here is to filter the output.

The 1N5402 Diode is used to make a rectifier circuit.

The Diode Rectifier is used to rectify the AC input into 12V DC.

The Current rating of transformer is 2-Amperes.

The 220 Volts Ac to 12 Volts DC current transformer is used to convert AC voltages to DC.

Connect the circuit input to Mains 220V AC 50/60 Hz.

The fuse is used for the protection of the circuit.

The basic purpose of 220v ac to 12v dc power supply project is to make a 12V DC output voltages to run DC applications.

Working Principle AC to DC converter Project: The diodes are used to rectify the output. As we know that whenever we convert from ac to dc we need a rectifier circuit. The transformer reduces the AC voltages from 220 to 12 volts.

Connect an AC wire plug at input and then a Switch and a fuse. This is also the AC to DC converter Project. The 220v ac to 12v dc power supply is easy and quite simple. The 12 Volt Fixed DC output is useful for many DC Controlled applications like DC motors, DC circuits, Pumps, Battery Chargers and many other useful applications. To convert 220V AC input into 12V DC output. What is a dc power supply and how we can define our objective as how to make a 12v power supply. Required Components for Power supply project.220v ac to 12v dc power supply Objective.
