This invention belongs to the field of wireless power transmission and civilian underwater equipment technology. Specifically, it is a portable autonomous underwater vehicle (AUV) wireless charging system using a grid-shaped three-dimensional orthogonal coil to achieve anti-rotational deviation. The system includes a primary-side grid-shaped coil array, an LCC-S topology circuit, a rectifier and filter module, rectangular coils, a planar coil array, limiting holes, and grooves. The receiving coil is integrated into the AUV's tail fin. Compared with existing technologies, this invention eliminates the need for complex control strategies and additional converters: it exhibits outstanding constant voltage output characteristics under a wide range of load variations; simultaneously, relying on the stable performance indicators of the LCC-S topology, it can flexibly adapt to different AUV docking positions, and its performance indicators remain stable within a deflection range of 0° to 20°. It directly eliminates the need for precise AUV alignment, providing a simple and highly reliable anti-rotational deviation solution for its wireless charging system.
