A lithium-ion battery charger is no simple device. So, if you learn what it takes to be able to build a DIY battery charger, you are drastically increasing your abilities, which is always a good thing. Also, Setting the current to maximum on a constant current voltage regulator makes that regulator no different than a constant voltage power supply.
Next, take a variable DC power supply. Adjust its output to precisely 4.1 V, which is the optimum full charge level of a standard 3.7 V battery. Connect this supply to the circuit from the left side, across the points where the battery is supposed to be connected. You will see the GREEN LED illuminating.
The transformer converts the 220V AC voltage to 30V AC. The rectifier converts the AC voltage to DC, which is then filtered using the electrolytic capacitors. The regulator (LM317) regulates the output voltage, and the output section delivers the output to the load. The circuit diagram for the Adjustable Power Supply is as follows:
With the help of two 2N3055 transistors, one LM317 Regulator IC, one BD139 transistor, and few other components, you can build your own cost-effective and customizable Adjustable Power Supply. The advantages of building your Adjustable Power Supply are numerous, and it’s an excellent way to get started with electronics.
