A novel power factor correction technique for a boost converter

The paper evolves a mechanism for improving the input power factor of an AC-DC-DC conversion system. It involves the process of shaping the input current wave to phase align with the input supply through a process of error compensation. The methodology includes cohesive formulation to arrive at nearly unity power factor and enjoy the etiquettes of output voltage regulation. The theory assuages to subscribe the benefits for the entire range of operating loads. It eliminates the use of passive components and fortifies the principles of pulse width modulation (PWM) for realizing the change in duty cycle. The MATLAB based simulation results arbitrate the viability of the proposed approach and exhibit its suitability for use in real world applications.
