9V Battery Charger / Power Supply Circuit

dc power supply Circuit (1)

The common power supply from all 9V and 12 Volts DC power. With the increasing use of LED lights, the use of DC power supply increased. Due to the need of DC power supply for LED lights. This DC power supply is required to charge all the batteries.

dc power supply Circuit (1)

DC power supply circuit (1) Here are the simple circuits shown. Electronics equipment needed here..

Part list :-

Capacitor 1000 MF 25V
Diode 1N 4003
Transformer 9v-0-9v

Description :-

First of all you need a transformer. How much of your voltage output is needed, buy a transformer depending on the voltage. Step down transformer has less than voltage in secondary. Step-up transformer rays have low voltage and secondary voltage is high. We'll use the step down transformer here. 9 voltage has been output to this transformer. Meaning of 9V-0-9V, 9 voltage will be output to the Right and Left and there will be no voltage in the middle, that means negative output. Transformer's positive Diode connection has to be done. And negative of the capacitor, the transformer will be added to the negative. And positive tow Diode of capacitor will be added. Connection is complete now the capacitor can be loaded on positive and negative connections.

Transformer

How to make Rechargeable LED Emergency light at home

Rechargeable LED

Emergency Light

Usually a rechargeable light is used after the power cut off. Darkness comes down after the light of day. Then there is a need of light everywhere in the village, city. The village power supply is not so much better than the city. After the power supply is cut off, the rechargeable light is needed.

How to create a rechargeable LED light at home?

To create a rechargeable LED light at home, there will be some things to bring from the market. The names are given below.

A plastic jar(Electrical wiring pvc board), six-volt battery, six-voltage LED light, Switch, Female Charging Jack, Wires will be required in some quantities.

Switch

The procedure to create this rechargeable LED light is discussed below.

Very simple connection :-

Electrical wiring pvc board.
LED strip lights
Switch
Charging socket
Wires

The connection I'm talking about here is very simple. Positive and Negative are all electronics devices. For this switch, the batteries, the LED's will have to put two wire. Only four connections will be put in the battery.

First comes the positive and negative battery connection from Female Socket. Battery connection with LED light positives and negatives.

Female Socket

Connection with charging LED :-

Electrical wiring pvc board.
LED strip lights.
Switch.
Charging socket.
Wires.
4007 diode.
100 ohm Resistor.
Charging indicator LED light.

This connection is complicated. But not too complicated. Here only a small LED needs, a Resistance and a Diode. Diode and Resistance adding to the charging socket positive. One side of the Resistance can be Charging indicator LED positive. Negative of Charging indicator LED and charging sockets will be linked together. The Diode can be switching positively one side and on the other side of the switch will be LED strip lights. Negative LED strip lights and Charging Socket will be added. Connection with one end of the Diode and one end of the LED strip lights will be connection with the Battery.

You can do many types of connections in this Rechargeable LED light. You can make more lights by adding more electronics parts. Lights can be controlled by adding Variables Resistor.
