Modelagem e Análise de Desempenho Comparativo sob Condições Iguais de Carga das Topologias Clássicas em Sistemas de Transferência de Energia sem Fio Indutiva

Abstract

This work presents the mathematical modeling, design methodology, and computational analysis of the classic inductive wireless power transfer topologies: Series-Series (SS), Series-Parallel (SP), Parallel-Series (PS), and Parallel-Parallel (PP). For a power transfer level of 500 W, the methodologies implemented in MATLAB®enabled the precise sizing of reactive components and power supply parameters, assessment of operational stability under misalignment conditions, and investigation of the bifurcation phenomenon. The results revealed distinct behaviors in efficiency, current and voltage stress, sensitivity to coupling variations, and design complexity, highlighting the importance of well-founded methodologies for the selection and optimization of these topologies. The comparative analysis provides a solid technical foundation for future implementations and enhancements of these systems, with prospects for experimental validation and expansion to more complex scenarios.
