In this tutorial, we are making an easy but important project, which is DC Power Supply. It is a 24V DC power supply circuit utilizing LM7824 IC. LM7824 is a 24 V 1.5 A fixed voltage controller IC, accessible in the TO 220 bundle. It is an IC of LM78xx arrangement, this arrangement contains many fixed yield voltage ICs like LM7815 is intended for a fixed 15 V yield and LM7818 is for a fixed 18 V yield. You can discover numerous different circuits of this arrangement ICs in the power supply circuits category. These ICs have many implicit highlights like short circuit protection, overheat protection circuits, and so forth.

Circuit Diagram
Circuit Operation
All the significant hardware has been worked inside the IC; therefore, very minimum external segments must make this project. As the schematic referenced above, utilizing just barely any capacitors. The transformer in the schematic is a 220 V to 24 V 2A transformer you can likewise utilize a 110 V to 24 V 2A transformer here. D1 is a 2A diode connect, and a 1N4001 diode is utilized to block feedback to the IC. The IC overheats during the activity because of which it requires a heatsink.
Applications and Uses
DC power supply is generally utilized in low-voltage applications, such as charging batteries, car applications, airplane applications, and other low-voltage, low-current applications.
