A EV Battery Charger Using a PFC based Bridgeless SEPIC Converter
Also Available Domains DC - DC Converters
Objective
The main objective of this paper is to design and implement an advanced control strategy for improving the performance, stability, and dynamic response of the proposed power electronic system under varying operating conditions. The study focuses on enhancing voltage regulation, reducing harmonic distortion, and improving overall system efficiency.
Abstract
Conventional PFC circuits in EV (Electric Vehicle) battery chargers have the efficiency limitation. To overcome this issue, there were losses associated with thw DBR, hence a bridgeless single ended primary inductance converter (SEPIC) with improved power quality is presented in this paper. Input current drawn by the charger shows a unity power factor operation in a complete switching cycle. Due to elimination of DBR, conduction losses are significantly controlled. The overall performance of the proposed bridgeless SEPIC converter is analysed with the help of various operating modes. The battery is charged at constant current/ constant voltage control mode and it provides satisfactory results for inherent power factor correction, thus, improving overall performance of the charger.
