Abstract:
This paper introduces of successful implementation of fuzzy logic controller (FLC) structure for an active clamp-coupled inductor-based soft-switched Quadratic Boost Converter. This proposed method aims to address several key challenges, including low sensitivity to input voltage variation, fast regulation during load transients, and robustness against aging effects on the converter's passive components. To solve all these issues a fuzzy logic controller (FLC) is designed, it is stated that utilizing a convergent distribution for the membership function leads to a faster response compared to symmetrically distributed membership functions. The robustness of the controller is evaluated under varying loading conditions and input voltage variations. Furthermore, the results are compared with conventional controllers (PI), showing superior dynamic performance. Simulink/ MATLAB is used to validate the performance of the controller.
