Learn to build a battery backup supply for small electronics so you never run out of power. There are a lot of electronics that need to be reliably on all the time. Alarm clocks are a good example of this.
Find a DIY power supply schematic for your electronic projects. Learn how to build and customize your own power supply with step-by-step instructions and diagrams.
This article discusses a simple uninterruptible power supply that can come in handy in various situations. The design contains a rechargeable Li-Ion battery, battery
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.
An uninterruptible power supply (UPS) is a device that ensures that the load stays powered even if the grid blacks out. On a very simplified diagram, you can see how the direct current standby UPS works. When there is power on a grid, current flows first via an ACDC converter and then via a DCDC converter to the output. The battery is charged
The circuit schematic (first picture) shows the battery power supply circuit. Look a little closer and you will notice that it is made of a few blocks. Scroll over each of these to see their function:

In this brief tutorial I have explained how to design a customized UPS circuit at home using ordinary components such as a few NAND ICs and a some relays.
The schematic for our power supply is incredibly simple and consists of: Input protection: used to protect our power supply and circuits connected to it; Power switcher: allows us to either use batteries or a wall
When the power supply is on, the battery sends its SOC to the PSU via UART. This is the simplified block diagram for the battery board. This board is responsible for charging and protecting the Lithium-Ion cells. The three main components are the BMS IC, the charging IC, and the microcontroller.

The schematic for our power supply is incredibly simple and consists of: The power supply shown below was built using a mix of wood and 3D printed parts. Originally, I intended to build the front face using wood and machining but it turned out that designing and printing a 3D model was much easier (mainly due to the lack of need for machining).
With the circuit design in hand, you can now start building your power supply. Begin by soldering the components onto a prototyping board or a custom PCB. Follow the circuit diagram and take necessary precautions to ensure proper connections and component placement.
Troubleshooting: Power supply schematics are also useful for troubleshooting issues with a power supply system. By following the flow of current and understanding the function of each component, it becomes easier to identify potential problems and find solutions.
This isn’t a problem if the backup power system is very rarely used. 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.
