A Novel Battery Charging In Electric Vehicle Using Non Isolated Zeta Converter
Abstract
This system proposes a non isolated zeta converter based high power charging in electric vehicle. In conventional battery chargers, diode-bridge rectifier plays a vital role in rectification. It has some disadvantages such as heat loss, number of diodes. Also it concentrates mainly AC-DC conversion alone. To maintain a unity power factor at transmission path, a novel ac-dc rectifier is needed. From above aspect, Vienna rectifier is presented. The main reason for choosing this method is to reduce ripple and THD in case observed in input; incremental action took upon input to meet load requirement and eliminates large filters. It is flexible and charges the battery by giving a steady state plow flow. In addition above two factors, a peak current control is further presented improves its advantages. A constant voltage magnitude is gained by this control topology. It adopts zero voltage switching and zero current switching. Additional proportional integral (PI) controller associated with single phase Vienna rectifier enables soft switching. These compact structures make electric vehicle industries to adopt this method. The simulink result viewing the power gain and how much amount of voltage gain attained and it is experimentally verified.
