Abstract

In complex environments such as mines and pipelines, wireless power transfer (WPT) technology stands as a safe and convenient method for supplying power. However, in practical applications, the unavoidable angular misalignment between the sending and receiving coils results in decreased power. To address this issue, this paper proposes a variable direction WPT design method based on auxiliary coils. The mutual inductance of the system is analyzed with coils placed at different positions and incorporating multiple auxiliary coils. This paper conducts simulation and experimental analysis based on a 45∘ angle between the horizontal shaft and the slant shaft, showing a 14.92% increase in received power. The effectiveness of the proposed design method validates the feasibility of the technology and offers substantial support for practical applications.
