This video explains about why we use PFC in SMPS, what it is and how does it work. In Switched-Mode Power Supplies (SMPS), Power Factor Correction (PFC) is a technique used to improve the efficiency and power quality of the power supply. PFC circuits shape the input current to be more sinusoidal and in phase with the input voltage, minimizing reactive power and harmonic distortion. This leads to reduced energy consumption, lower electricity costs, and compliance with power quality regulations.

Benefits of Active PFC in SMPS:
High Power Factor: Can achieve power factors close to 1, indicating near-perfect power utilization.
Wide Input Voltage Range: Many active PFC circuits can automatically adjust to different input voltages (e.g., 100V to 240V).
Reduced Size and Cost of Passive Components: Active PFC allows for smaller and less expensive passive components in the SMPS.

In total, PFC is a crucial feature in modern SMPS designs, enhancing efficiency, reducing energy consumption, and ensuring compliance with power quality standards.
