Automatic Power Factor Correction (APFC) Controller Project Using 8051 Microcontroller | APFC Project

The Automatic Power Factor Correction (APFC) Controller using 8051 Microcontroller is an innovative and practical electrical engineering project created to automatically correct the power factor in electrical systems.

⚡ A low power factor leads to higher energy losses, increased electricity bills, and sometimes even utility penalties. This intelligent project tackles the problem head-on by automatically switching capacitor banks based on the changing load conditions — ensuring efficient energy use and cost savings.

The Automatic Power Factor Correction (APFC) Controller using 8051 Microcontroller is an innovative and practical electrical engineering project that automatically corrects the power factor in real time. A low power factor increases current draw, causes higher transmission losses, and can even trigger utility penalties. This intelligent system continuously monitors power factor and switches capacitor banks to keep it close to unity—improving efficiency and cutting energy costs. 💡
