Abstract
The design and analysis of higher efficiency non isolated DC-DC converter for Electric Vehicles is presented. A Battery Charging System (BCS) plays a key role in achieving fast charging and higher efficiency. The BCS integrates acascaded DC-DC converter and a bidirectional PWM converter. In order to achieve more reliability and stiff voltage, aCascaded buckboost converter which is partitioned with the help of a capacitor is integratedand to achieve higher efficiency with less number of switches, a bidirectional PWM converter used There are various PWM techniques, among them hysteresis and sinusoidal pwm technique are used. The output voltage obtained after both the operations (boost and buck) is given to the battery or load. Simulation is done in MATLAB and the results are analyzed with PI controller and without PI controller in this paper.
