Introduction
The design and implementation of a power factor correction (PFC) system using a boost converter controlled with a PID (Proportional, Integral, Derivative) controller optimized by Particle Swarm Optimization (PSO) algorithm. Traditional PID controllers require manual tuning, but PSO automates this process to achieve better transient response and steady-state accuracy. The boost converter shapes the input current to minimize harmonic distortion and improve power quality, making it suitable for both industrial and commercial power systems.
Objectives
