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

Image
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 We are going to make battery cha
