    In this study, a novel power boost converter topology, which is characterized by a single-switch configuration and its connection to a battery, is introduced. The primary objective of this study is to explore its suitability for voltage enhancement in electrification transportation systems. An intrinsic advantage of the proposed converter lies in its ability to provide a continuous current output with a constrained magnitude, consequently reducing peak values on the battery input side current as a critical parameter impacting battery reliability and longevity. Furthermore, the gain achieved by this novel converter is substantial, rendering it a viable choice for high-voltage Vehicle-to-Grid (V2G) applications.Unlike traditional boost converters, which usually produce an output voltage twice that of the input voltage with a duty cycle of 0.5, the suggested converter exceeds this by providing an output voltage five times higher than the input voltage. The validity of the theoretical framework is substantiated through mathematical derivations and simulation outcomes. To control the proposed converter effectively, a fuzzy logic controller is employed, chosen for its suitability in managing nonlinear systems and its simplicity of implementation. © 2023 IEEE.
