How to Make a Simple Battery Charger With Bridge Rectifier Circuit?

Here you can read how to make a simple charger or adapter for charging 6 volt rechargeable battery. This charger works with a bridge rectifier circuit and a step down transformer. You can use this device as a AC adapter or charger for batteries. By selecting proper transformers and rectifier circuit it is possible to change the output of the charger. Thus you can design a charger circuit according to your purpose.

What is a Step Down Transformer?
Transformer is a device used to step up or step down the input voltage. A step down transformer reduces the input voltage and provide a lower voltage at output. A transformer works on the principle of mutual induction.

What is a Rectifier Circuit?
The output of a step down transformer is an AC voltage. But we need DC of the same voltage. A rectifier circuit is used to convert the AC voltage to DC. There are three main types of rectifier circuits.

1. Half wave rectifier
2. Full wave rectifier
3. Bridge rectifies
