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
- To develop a boost converter-based power factor correction system.
- To implement a PID controller with parameters optimized using the Particle Swarm Optimization algorithm.
- To achieve near unity power factor and low total harmonic distortion (THD) in the input current.
