Design a Bidirectional DC/DC Converter for Second-Level Electric Vehicle Bidirectional Charger

Electric Vehicle (EV) has derived into consideration within automotive manufacturing over the last centuries. The charger of EV contributes significant part in the growth of EV. This paper proposes DC/DC converter which can be integrated for application in second- level electric vehicle charging. Further, the proposed converter is bidirectional, accomplished of delivering power from batteries to the grid which called vehicle-to-grid (V2G) applications. The DC-DC converter is molded by mixing buck and boost converters and accordingly it is capable to function in buck as well as boost methods in both ways (charging and discharging). Throughout charging (G2V) the voltage (Dc-link) is stepped to down by the DC-DC converter to battery volt age and delivers requisite charging current by current control (CC).This is buck process through charging. While V2G process the role of the DC-DC converter is to boost the battery voltage to deliver the dc link voltage. The converter is predictable to get high efficiency.
