Abstract

This project presents a new transformer less quadratic buck-boost converter designed to provide high voltage gain while ensuring continuous input/output current. The proposed converter overcomes the challenges of traditional buck-boost converters by delivering a wider voltage conversion range, enhancing the overall efficiency and performance of the system. A Fuzzy Logic Controller (FLC) is integrated to optimize the converter’s operation. The FLC effectively manages the voltage regulation by adapting to varying input conditions and ensuring constant output voltage despite fluctuations in the input. It also minimizes current ripple, providing smoother operation and reducing component stress. The adaptive nature of the FLC ensures better performance under dynamic load and input conditions, compared to conventional control techniques. Simulation results demonstrate the converter's high efficiency, improved voltage regulation, and stable performance under different operational conditions. The proposed transformer less quadratic buck-boost converter shows significant improvements in power quality and efficiency, making it a promising solution for renewable energy systems, electric vehicles, and energy storage applications.
