6V Backup Power supply With Rechargeable Battery
The following circuit is a 6V backup power supply using a voltage regulator IC 7805. This circuit is suitable for use in areas that often cut off the electricity because it is equipped with a backup battery system. A rechargeable battery 6V is used as energy reserves and is automatically recharged when not in use.
In this power supply circuit, there are two essential elements of the DC power supply with AC transformer and DC Power supply that comes from a rechargeable battery (e.g. . DC power supply with a transformer is as a regular power supply system.
Power supply circuit equipped with a spare battery is very attractive and simple to construct. Description of component values can be seen in the power supply schematic below.
Backup Power Supply
You can change the power supply circuit with a larger capacity, replace the AC transformer and adjust the diode, and the final power transistor. Replacement Battery by selecting a larger capacity. Congratulations to experiment.
