Design of CCM boost converter using fractional-order PID controller optimized with gray wolf algorithm for power factor correction

The primary determining elements for the effective operation of power electronic converters are power quality (PQ) in terms of power factor, total harmonic distortion (THD), and ideal output regulation. The uncontrolled diode bridge rectifier draws pulsed input current, which may be managed with an easy and efficient active wave shaping control system in this study, bringing the power factor (PF) closer to unity and meeting the THD parameters. It controls the generated voltage as well. The goal of this study is to create a CCM boost converter-based active PFC control circuit that uses fractional-order PID control and gray wolf (GW) optimization that has higher robustness with lower sensitivity to error. The suggested plan uses a cascade controller providing adequate operation and results for upholding PQ. Additionally, the fractional notion has many benefits, including greater robustness to shocks and decreased sensitivity to inaccuracy. Simulation findings that guarantee significant tracking of the reference signal with a decreased rate of THD have been shown.
