Development of a Bidirectional Dc-Dc Converter for Electric Vehicle Charging

Abstract

Over the last few centuries, discussion of electric vehicles (EVs) has evolved within the automobile industry. The rise of EVs is significantly aided by their charger. This study suggests an integrated DC/DC converter for use in second-level electric car chartering. So, the suggested converter is bidirectional, capable of providing electricity from batteries directly to the grid is dubbed Vehicle to Grid (V2G) utilisations. Also, the DC-DC converter is created by combining boost and buck converters, and as a result, it can operate in both boost and buck techniques for charging and discharging. The DCDC converter steps down the voltage (Dc-link) while charging Grid to Vehicle (G2V) to battery voltage and provides the necessary charging current through CC. This is the charging step in the buck process. The DC-DC converter's function throughout the V2G procedure is to increase the battery voltage in order to supply the dc link voltage. It is foreseeable for the converter to achieve high efficiency.
