Using the battery backup circuit that I designed, you can plug your power supply into a female DC power connector. This is connected to the battery backup circuit. Then at the output of the battery backup circuit, there is a male DC power connector that can plug into the electronic device that you want to power.
In this tutorial, we are making a circuit of a 12V Battery Backup Power Supply. This circuit will automatically shift the load to the battery in the absence of the main supply. When the mains supply is back the load will shift to the mains supply and the battery will go into charging mode automatically.
First, you need a DC power supply. These are very common and come in a variety of voltages and current ratings. The power supply connects to the circuit with a DC power connector. This is then connected to a blocking diode. The blocking diode prevents electricity from the battery backup system from feeding back into the power supply.
2 x Diode (rated for a higher current than the power supply) Male DC Connector Female DC Connector There are many different kinds of battery backup systems, and the type that you use is largely dependent on what you are powering.
Next, a rechargeable battery is connected using a resistor and another diode. The resistor allows the battery to be slowly charged from the power supply, and the diode provides a low resistance path between the battery and the circuit so that it can power the circuit if the voltage of the power supply ever drops too low.
Connect an adjustable power supply. Set the voltage of the adjustable power supply to 14.4V. Remove the battery and the transformer and connect the power supply in the place of the battery. Adjust the 10K variable resistor until the LED glows. Connect your battery and the transformer back to where they were and remove the adjustable power supply.
