The increasing demand for uninterrupted electrical power has created the need for reliable automatic power source selection systems. This project presents a Multi-Power Supply Using Four Different Sources – Priority-Based Source Selection to Load, which ensures continuous power supply by automatically selecting the highest-priority available power source. The system is built around a microcontroller that continuously monitors the availability of four different power sources. Based on a predefined priority sequence, the controller automatically switches the load to the highest-priority source using relay drivers and relays. If the primary source fails, the system immediately transfers the load to the next available source without manual intervention, ensuring uninterrupted operation. The selected power source is displayed on an LCD, while LED indicators provide visual status of the active source. Selection switches allow manual configuration of source priorities when required. The system uses a regulated power supply, crystal oscillator, and reset circuit to ensure stable and reliable operation. This project provides a cost-effective, efficient, and reliable automatic power management solution for homes, industries, hospitals, communication systems, and other applications where continuous power availability is essential.        

Objectives of the Project:  
  1. To develop an automatic power source selection system using a microcontroller.
  2. To monitor the availability of four different power sources continuously.
  3. To automatically supply power to the load from the highest-priority available source.
  4. To switch to the next available source when the current source fails.
  5. To display the selected power source on an LCD and indicate its status using LEDs.
  6. To provide a reliable, uninterrupted, and cost-effective power supply for the connected load.
