Abstract: This paper presents a novel control strategy for output tracking in a DC/DC step-up converter, elevating the standard of precision and performance metrics. Beyond achieving commendable results, such as low Root Mean Square Error and rapid settling times, our novel approach ensures a seamless absence of overshoot, marking a significant advancement in both static and dynamic performance. A meticulous theoretical exploration forms the foundation of our proposed control methodology. Notably, our strategy excels through the integration of three pivotal factors: (i) a sophisticated small-signal model designed to operate seamlessly within the broad spectrum of the converter's operational range, (ii) the deployment of full-state feedback control, and (iii) the innovative incorporation of the Takagi-Sugeno fuzzy approach. Building upon a comprehensive understanding of the boost converter's topology, operational principles, and theoretical modeling, this paper delves into the intricacies of our suggested output control technique. The utilization of full-state feedback control and the Takagi-Sugeno fuzzy approach further reinforce the strategy's robustness, adaptability, and stability across diverse operating conditions. Simulations conducted in the Matlab/Simulink environment showcase the remarkable capabilities of our proposed control system, the precise reference tracking, resilience against input fluctuations and load disturbances, and unwavering compliance with performance requirements, our approach solidifies its status as a pioneering solution throughout the entire operational range of the system. In summary, our research not only introduces a state-of-the-art control approach but also underscores its effectiveness in achieving good static and dynamic performance metrics, thus contributing significantly to the advancement of DC/DC converter design.

Abstract: Now a days, inductive power transfer (IPT) has gained a lot of attention from researchers as it has ease of use and realiability for electric vehicle (EV) battery charging systems. This paper examines the increasing attention from researchers towards inductive power transfer (IPT) as a means of charging electric vehicle (EV) batteries. This interest originates from the user-friendly characteristics and notable reliability associated with IPT. The evaluation of mutual inductance (MI) holds importance within the domain of Inductive Power Transfer (IPT) systems, as it serves a critical function in enabling effective power transfer. Therefore, it is essential to perform a comprehensive analysis of the mutual inductance between the two coils that are connected through inductive coupling. This study provides an examination of mutual inductance (MI) and efficiency within the context of interoperability conditions of interconnected coils. The transmitter coil is represented as a square structure, denoted as TxS, whereas the receiving coil is represented as a circular structure, denoted as RxC. Furthermore, the application of ferrite cores and steel chassis inclosures, in combination with coils, is utilised for the objective of electric vehicle (EV) battery charging. The magnetic induction (MI) analysis is performed by the utilisation of finite element method (FEM) simulation. The finite element method (FEM) simulation outcomes of the interconnected coils with misalignments, encompassing both non-core and steel chassis configurations, are juxtaposed with the corresponding empirical observations.
