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

  1. Diode = 4 Nos
  2. Step Down Transformer = 1
  3. Capacitor = 1 No

How to Make an AC to DC Converter using Diode

Following are the Steps:

  1. 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.Step Down Transformer
  2. 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.
