Design of CCM boost converter using fractional-order PID and self-tuning schems 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. In this study, the uncontrolled diode bridge rectifier draws pulsed input current, which can be managed with an easy and efficient active wave-shaping control system, bringing the power factor closer to unity and meeting the THD parameters. It controls the generated voltage as well. A robust adaptive controller is selected for this work with stability ensurance and significant robustness against ditusrbances, particularly noisy cases. The controller structure consists of an Inner loop and an outer control loop. In the inner loop, the Self-Tuning Regulator controller is used because the Inductor current varies with time. A Fractional-Order Proportional-Integral-Derivative controller is used for the outer loop. The parameters of this controller are optimized by the Ant Lion optimizer algorithm. The suggested plan uses a cascade controller providing adequate operation and results for upholding PQ. The controller designed in this work has stable and robust performance against noise, uncertainty, and other factors. These findings confirm the co-design techniques.
