Abstract - The amount of exhaust gases increases with the increasing use of vehicles with internal combustion engines. To reduce CO2 emissions, researchers and industry are working to improve electric vehicle technology around the world. This paper deals with the design and simulation of a bidirectional power converter for electric vehicles. The electronics block consists of batteries, a bidirectional DC-DC converter and a DC motor. The initial state of battery charge is set at 90% where the discharge current is 44.5 A in motor mode. The nominal voltage of the battery stack is 350 V and the maximum capacity is 100 Ah. The rated power of the DC machine is set at 250 HP with 500 V armature voltage and 300 V field voltage. The operation mode of the power converter is determined according to the torque value of the DC machine which is operated in motor and generator mode. Battery charging and discharging conditions have been controlled with respect to DC motor operating modes. The bidirectional dc to dc converter is controlled by fuzzy logic in both modes. The proposed converters and controllers are designed to meet the charging control and motor drive requirements for electric vehicles.
