Power Factor Correction Circuit and Output Analysis Based on Rejection Harmonies

The aim of the project is to develop a buck-boost converter that improves the input power factor of AC power supplied by activating the AC input current waveform. The
main functionality of the project is to provide a near unity power factor for the buck-boost operation and reduce the total harmonic distortion. Due to increase in the use of converters in industries and home, low power factor conversion results in
huge losses of power. To fill this gap, a near unity power factor is designed for the buck boost operation. The project will solve the problems of manual monitoring and provides a platform to perform actions without the presence of user near the
hydroponics system. For PFC BBC, the suggested control methodology utilizes a Proportional-Integral (PI) controller in the outer voltage loop and an Inductor Average Current Mode Control (IACMC) controller in the inner current loop. The
IACMC has several advantages, including its robustness when line voltage and output load fluctuate significantly. The PI controller is designed using the BBC's state space average concept. MATLAB/Simulink is used to simulate the proposed
system and its control circuit. The simulation findings indicate that a power factor close to unity can be achieved and that there is virtually no change in power factor when a different duty cycle is applied.
