on video 220V AC to 12V DC Converter Power Supply Using Diodes, Capacitors, Resistors, & Transformers


 This electronics video tutorial explains how to build a 12V DC power supply using a 220V AC power source, conventional diodes, zener diodes, capacitors, resistors, and a transformer.  The step down transformer brings the 220V AC voltage to 13V AC.  The conventional germanium diodes form a full wave bridge rectifier converting AC to DC.  The zener diode acts a voltage regulator and the capacitor reduces ripple voltage and converts the pulsating DC wave into a smooth DC output.  The series current limiting resistor reduces the surge current that flows through the diode when the capacitor is charging.

How to Convert AC to DC using Diode

Here we Learn How to Convert AC to DC using Diode, Transformer, Capacitor, Bridge Rectifier. Make DIY AC to DC Converter using Diode.

What is a Diode?

A Diode is an electronic component that allows electric current to flow in one direction only. It is a semiconductor device that consists of a p-n junction. Diodes one of the most basic semiconductor devices.


Common Application of Diode

Diodes are most commonly used to convert AC to DC, because they pass the positive (+) part of the wave, and block the negative (–) part of the AC signal, or, if they are reversed, they pass only the negative part and not the positive part.

Both p-type and n-type silicon will conduct electricity just like any conductor; however, if a piece of silicon is doped p-type in one section and n-type in an adjacent section, current will flow in only one direction across the junction between the two regions.


Electronic Components needed to Convert AC to DC

Diode = 4 Nos

Step Down Transformer = 1

Capacitor = 1 No

Take a Step Down Transformer. If the Input AC is 240 Volt and Required DC Output is 24 Volt, then we need a 240/24 Step Down Transformer.

Now connect the 4 Diodes in the Following Way – Anode (Positive +) to Cathode (Nagative -). 4 Diodes connected in this format will form a Bridge Rectifier.

Now take a Capacitor and Make connections as per the following diagram.

Now your AC to DC Converter using Diode is Ready.
