摘要：Electric vehicles are gaining importance in the present situations as it is the most reliabletransportation system in near future with less environmental pollution, fuel economy and energy efficiency. Theconcept of microgrid and smart grid has added a rage to distributed generation and increased communicationbetween customers and utility. The idea of bidirectional interaction between grid and Electric vehicle has broughtthe V2G,V2H etc. technologies . Bi- directional chargers adds the benefit of EVs by enabling energy transfer fromvehicle to grid (V2G) or vehicle to home (V2H) in addition to charging from grid to vehicle(G2V).TypicallyBidirectional chargers consists of a AC-DC stage followed by DC-DC stage. This paper presents a non isolatedintegrated bi-directional DC-DC converter for interfacing the vehicle battery to the DC link in both charging modesand discharging modes. The DC-DC converter is formed by integrating buck and boost converters and thus it is ableto operate in buck as well as boost modes in both direction (charging and discharging). During charging (G2V) thedc link voltage is stepped down by the DC-DC converter to battery voltage and provides required charging currentby current control. This is buck operation during charging. During V2G or V2H operation the function of the DCDCconverter is to boost the battery voltage to provide the DC link voltage.
