摘要

The growing market of electric vehicles requires efficient and dependable charging solutions. Conventional converters are usually AC-to-DC that face problems such as power efficiency, high component stresses, and suboptimal regulation during varying load conditions. To overcome these concerns, this work proposes an isolated SEPIC converter with double switches for EV charging applications. It uses the principle of isolation for higher safety along with the application of the topology of dual switch in the circuit for increased efficiency with minimal switching losses. This ensures robust performance along with power density. The designed system solution can be perfectly merged into an EV charging station while also offering features like compactness, scalability, and a significant increase in the conversion of energy. This work aims at optimizing electric vehicle charging infrastructure by minimizing wastage of energy through an effective charging system by working out the limitations that currently exist.
