This technical talk is one of two talks in the Electric Vehicle Talk Series.

With the growing demand for electric vehicles (EVs), efficient on-board charging systems have become imperative. Power Factor Correction (PFC) converters play a crucial role in enhancing the performance of these systems. By improving the power quality and efficiency of the charging process, PFC converters contribute significantly to EV charging infrastructure's overall functionality and reliability. PFC converters optimize the power factor by minimizing reactive power consumption, thereby reducing energy losses and enhancing the utilization of the electrical grid. This results in faster charging times and reduced operational costs for EV owners. Additionally, PFC converters help meet regulatory requirements for power quality and grid stability, ensuring seamless integration of EVs into existing electrical infrastructure. 

The integration of PFC converters in on-board charging systems enables EVs to draw power efficiently from various sources, including residential outlets and public charging stations. This versatility enhances the convenience and accessibility of EV charging, addressing concerns about range anxiety and infrastructure limitations. Furthermore, advancements in PFC converter technology, such as wide band gap devices (WBG) that include silicon carbide (SiC) semiconductors, offer higher efficiency and power density, further improving the performance of on-board charging systems. These innovations enable faster charging rates while reducing the size and weight of charging equipment, making EVs more practical and appealing to consumers. 

In conclusion, the implementation of PFC converters in on-board EV charging systems represents a significant step towards achieving efficient and sustainable transportation solutions. By optimizing power quality, improving efficiency, and facilitating rapid charging, PFC converters play a vital role in accelerating the adoption of electric vehicles and transitioning towards a greener future. The research examines the customized pulse width modulation (cPWM) based converter topologies for electric vehicle charging purposes. By using the proposed cPWM gating technique the device stress gets reduced which proportionally enhances the lifetime of the converter topology. The proposed unidirectional topology pursues the soft-switching behavior over full battery charging range and the voltage spikes across the rectifier diodes are also mitigated with proper selection of switches at a particular frequency. This phenomenon enhances the efficiency of the converter in a cost-effective way.
