Abstract

As a novel power supply method, single-wire power transfer has gained a great deal of attention. However, most of the related studies were based on using loops to realize a two-way power transfer. To further develop single-wire power transfer technology, a single-wire power transfer method is proposed in this paper, which does not rely on loops for power transfer. Through theoretical derivation, its transfer principle is analyzed, and a single-wire power transfer structure is designed. In addition, the theoretical derivation is verified by simulation analysis. Finally, the factors and laws that affect transfer efficiency are obtained through simulations and experiments. The research conducted in this paper is conducive to the development of single-wire power transfer methods, and lays a foundation for further research on transfer characteristics.
