Bridgeless Cuk Converter based EV Charging Unit for Better Power Quality and Efficiency

As the number of electric vehicles on the road continues to rise daily, there has been a recent surge in the use of renewable-based charging stations and electric vehicles (EV). The charger is a crucial component of the infrastructure for electric cars because it converts AC electricity into energy, which requires batteries the main source of power for vehicle of power for vehicles. In a previous study, the control method addressed a number of issues such as low power quality when connected to the grid output demand, intermittent power supply in the converter, safe and efficient battery charging, and distortions in a particular type of charging unit. This limitation was addressed in this study using an upgraded Bridgeless (BL) Cuk converter-based EV battery charger. The signals for battery charging are coordinated across regions with constant voltage and current using a flyback converter. The PWM evaluation of low-frequency signals is ignored, and high-frequency signals may pass through high-pass filters before they undergo amplitude or attenuation. The test results show that the output of the proposed charger improves the power quality and supports the improved performance of the optional battery charger.
