Improving energy efficiency and power quality are two key advantages of using a Boost Converter system equipped with Power Factor Correction (PFC). This technology is increasingly adopted in electric vehicle (EV) charging stations due to its ability to deliver stable DC power with high power factor. However, a major challenge arises during system start-up, where the sudden charging of the DC-link capacitor can trigger a high inrush current. This surge can potentially damage key power components such as rectifier diodes, capacitors, and switching devices, while also reducing the overall lifespan of the system. This study aims to design and evaluate a method for mitigating inrush current by implementing a common mode current filter, strategically placed at the input stage of the boost converter. Simulations were carried out using PLECS software to observe the transient behavior of current and voltage during start-up conditions. The results show that the proposed common mode filter effectively reduces the peak inrush current by more than 85% compared to an unprotected system. These findings highlight the filter's potential to enhance the reliability, safety, and operational longevity of PFC-based EV charging systems. © 2025 IEEE.
