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.
The red wire is connected to the positive side of the battery and the black wire is connected to the negative side of the battery. When using as an adjustable DC power supply, you need to use an DC Power Supply Output Port I marked in image 66 and PUSH the switch to the right side.
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:
Open the computer case. You should be looking at the computer's internals at this point. Lay the computer case on its side, with the exposed side facing up. Set the power supply's voltage switch. If there's a voltage switch on the power supply, switch it to the 110v or 115v setting.
Keep in mind that if your computer came pre-assembled, you don't need to install the power supply, though you may eventually need to replace it. Ground yourself and open the PC case. Set the voltage on the power supply to 110v or 115v. Insert the power supply and screw it into place. Attach both power cables to the motherboard.
The advantages of building your Adjustable Power Supply are numerous. Firstly, it’s cost-effective. You can save a lot of money by building your own Adjustable Power Supply rather than buying one from the store. Secondly, it’s customizable. Since you are building it yourself, you can customize it according to your specific needs.
