Design a Electric Vehicle Charger Based Sepic Topology with PI Controller

Abstract

The solar panels are extensively used in both rural and urban areas to generate electric power from sun light energy, if the light energy is low the output voltage of the solar panel is also less. The battery will not charge as it is lower than the rated charging voltage. This happens most of the time in a day due to cloud condition, monsoon season and shading effect. Hence by implementing a controller based SEPIC converter, the voltage produced at the lower from solar panel can also be utilized effectively by boosting/bucking it to the rated charging voltage of the battery. This paper was to design and optimize an electric vehicle charger based SEPIC dc/dc converter. This converter single ended primary inductance converter. The SEPIC converter allows a range of dc voltage to be adjusted to maintain a constant voltage output. This paper talks about the importance of dc-dc converters and why SEPIC converters are used instead of other dc-dc converters. This paper also goes into detail about how to control the output of the converter with PI controller to show how it can be implemented in a circuit using Matlab software.
