How to make 6v12v Transformer battery charger circuit

Charger circuits can be made in a variety of ways. The charger circuit is needed to charge the battery. Whether it is 6v battery or 12v battery. Today I will show you how to make a charger circuit with a transformer. Charger circuits can be made in different ways with the help of transformers and diodes. Today I will show you how to make charger circuits. Let’s find out the components that are needed to make a charger circuit with the help of a simple transformer.

  1. Transformer.
  2. 1N4007 Diode.
  3. Capacitor.
  4. Led.
  5. Resistance.

You can create a charger circuit in a simple way with these components. The charger circuit that is made with the diode is called the rectifier. Now let’s find out how many types of rectifiers.

  1. Half wave Rectifier.
  2. Center tap full wave rectifier.
  3. Full Wave Bridge Rectifier.

Half wave Rectifier:

Half wave rectifier is made with the help of a diode. An electrolytic capacitor is inserted after the diode for filtering. But it is not possible to make Pure DC in a half wave rectifier. Its output is available on the web in the form of pulsating DC i.e. complete DC current is not available. Below is the connection diagram / circuit diagram of how to make a half wave rectifier.

See in the picture above I have seen how to make a half wave rectifier. This half wave rectifier circuit is not pure DC. This is why it can be used to charge the battery, but the battery does not last long.

Center tap full wave rectifier:

Center tap full wave rectifier is made with the help of two diodes. The center tap transformer is required to make this charger circuit i.e. the output of the transformer has three wires. It is a widely used charger circuit. I showed the following circuit diagram or connection diagram.

Electrolytic capacitors are used for filtering this circuit. With this circuit it is possible to make a fairly pure DC. With the help of this circuit, DC web is available at the output for both half cycles of AC web. It works well as a charger. This circuit is widely used for this.

 

Full Wave Bridge Rectifier:

Full Wave Bridge Rectifier circuit is mostly used as charger. Four diodes are used in this circuit. For this it is possible to make Pure DC at the output of this circuit. Below is the circuit diagram / connection diagram of this circuit.

Electrolytic capacitors are used for filtering this circuit. With this circuit it is possible to make a fairly pure DC. With the help of this circuit, DC web is available at the output for both half cycles of AC web. The most popular circuit as a charger is the full wave bridge rectifier circuit .All types of charger circuits are made based on this full wave bridge rectifier.
