The fuzzy-controlled single-stage Zeta–SEPIC converter architecture designed and built for this project intends to increase the dependability, power quality, and charging speed of next-generation plug-in electric vehicles. The proposed technology integrates the most advantageous attributes of the Zeta and SEPIC converter topologies into a single system. This simplifies voltage control by reducing energy loss and component quantity. Fuzzy logic control enables the converter to respond more rapidly and adapt to fluctuations in input and load conditions in these circumstances, whereas conventional control methods are less effective at managing these changes. In summary, our research establishes the foundation for the development of high-performance, intelligent, and compact power conversion systems that can be implemented in contemporary electric vehicles.
