Resumen

This paper presents a comparative analysis of two inductive wireless power transfer (IWPT) topologies, focusing on their application in underwater environments. The study compares the widely used planar spiral coil with an innovative split core transformer topology, employing finite element simulations to evaluate their performance, advantages, and disadvantages in near-field applications and underwatersettings. The research addresses the challenges associated with underwater wireless power transfer (UWPT), such as misalignment, radiation losses, and high-pressure conditions. Different coil topologies are discussed, with an emphasis on their design considerations for efficient power transfer underwater.The study includes an overview of the IWPT circuit and design considerations for the underwater environment. Finite element method (FEM) studies are conducted for both planar spiral coils and split core transformers, assessing their efficiency, separation tolerance, and performance under increasingfrequencies. The results highlight the strengths and limitations of each topology, providing valuable insights into their respective viabilities for underwater applications.
