Design and Analysis of Predictive control using PI controller for Boost Converter with Active Power Factor Correction

Power factor correction of boost converter is done by using predictive control strategy. In this paper predictive control algorithm is presented based on this algorithm all of the duty cycles required to achieve unity power factor in one half line period are calculated in advance by proportional Integral (PI) controller, the simulation results show that the proposed predictive strategy for PFC achieves near unity power factor. The power factor and input current distortion are analyzed using with control and without control techniques. Simulation results are shows that the power factor is higher than 0.99, and current total harmonics distortion (THD) is smaller than 20% under full load condition.
