EFFICIENCY IMPROVEMENT OF ELECTRIC VEHICLE BY USING ACTIVE FILTERS

In electric vehicle is new emerging trend, because cost of fuel is increasing and air pollution is also increasing. Electric vehicle is control the air pollution. Electric vehicle also gives less cost per kilometer. Electric vehicles can run up to 450 km in a single battery charge to achieve this distance normal fuel consumes very large amount of fuel giving rise to costly journey as well as rise in air pollution but in case of electric vehicles does not pollute air and have high fuel efficiency because of this it is very beneficial for the society. In electric vehicles battery pack is uses to give power to electric motors. Battery is dc supply. Inverter is converted DC to impure AC supply having large harmonics, these harmonics reduces the efficiency of electric motor that as electric vehicle. This work shows some MATLAB simulation of inverter has done 21 levels. This simulation gives approximate output. As a result, THD reduce.
