Abstract: Electric Vehicle (EV) batteries are participated in the regulation of power flow in grid through battery charger. In this paper Bidirectional battery charger of 12-V,4A, 32W is proposed. The Bidirectional battery charger circuit comprises of two-stage conversion i.e. DC-AC and AC-DC conversion. Neutral Point Clamped (NPC) converter is used for Bidirectional AC-DC conversion. The battery charger can convert three phase convenient power to charge the batteries of vehicles by providing 12-V, 4A  . Likewise, the battery charger can discharge back from the connected battery to the load when there is power demand of load in the grid. 

Keywords: Electric Vehicle, Bidirectional battery charger, Neutral Point Clamped
