Bidirectional DC-DC Converter for an On Board EV Battery Charger with V2H Application

Vibhav Khedekar, Dr. Laxman Rao S. Paragond and Prakash Kulkarni

Power electronics based power converters are used to charge High voltage traction battery of Electric vehicles from the grid. The same battery can also be discharged using bidirectional converter and energy can be fed back to the grid. Such a bidirectional converter consists of front end bidirectional AC-DC converter followed by a bidirectional DC-DC converter. This paper focuses on control strategy of the Dual Active Bridge (DAB) bidirectional DC-DC converter to regulate battery charging and discharging process.
