Abstract: This paper mainly emphasis on modelling and simulation of charging of electric batteries through Single Phase On-board Bidirectional Charger for Electric Vehicles. The charger resides of: i) two AC-DC full bridge bidirectional boost converter (120V AC to 400V DC); and ii) a half bridge DC-DC buck converter. The AC to DC full bridge boost converter and DC-DC buck converter has been developed for charging purpose. The controller for both converters has been designed. The motive of AC-DC converter controller is to supervene the Active and Reactive Power (P-Q) commands provided by grid or utility. With the change in controllable commands the parameters of DC side can be adjusted. For each converter a separate controller is provided that maintains the balance between input power and output power. The controller for AC-DC converter helps to boost up the input grid voltage up to 400V DC. The charger must have to supervene the instructions/commands provided by grid or utility. The DC-DC converter is used to proselyte fixed voltage into variable voltage so that current required for charging the battery can be restrained. Work in this manuscript mainly focuses on Level-1 and Level-2 On Board charging system. The proposed single phase PEV charger is used to charge the Plug-in hybrid Electric Vehicles (PHEV) and Battery Electric Vehicles (BEV) in charging only operation. The charging system for EVs has been simulated and State of Charge (SOC) obtained are compared with the existing three developed charging systems.
