A Novel Variable Width PWM Switching Based Buck Converter to Control Power Factor Correction Phenomenon for an Efficacious Grid Integrated Electric Vehicle Battery Charger (original) (raw)

—This paper proposes an innovative approach to utilizing Buck converter as an ideal Power Factor Correction (PFC) controller where variable width Pulse Width Modulation (PWM) switching signals are generated and implemented to reliably control the voltage and current conversion phenomena. The developed converter topology is tactically utilized to design an efficacious grid-connected electric vehicle charger with substantially ameliorated line Power Factor so that the system loss can be averted in the case of AC-DC charging circuits. In order to ensure the sustainability of the proposed method, PSIM simulation software has been used to emulate a simulation model of a Battery charging system for Electric vehicles. The simulated output and evaluated performance parameters provide almost unity Power Factor (PF) with a Total Harmonic Distortion (THD) rate of 4.62% which is lower than the maximum allowable value recommended by IEEE519. The simulation outcome corroborates the efficiency and validity of the proposed framework.
