[Abstract]:With the increasing number of consumer electronics in daily life, people yearn for a convenient home charging platform which can accommodate multiple devices. As a new technology, the innovation of wireless energy transmission (WPT) technology in power supply has attracted much attention. In particular, the magnetically coupled resonant radio energy transfer (MCR-WPT) technology, which has the advantages of safety, simplicity, medium distance transmission and high efficiency, can be well applied in home and office environments. With this technology, the charging platform can effectively supply wireless power to multiple mobile devices at the same time, so it has a broad research prospect. A resonant multi-load wireless charging system with isolation characteristics is studied in this paper. The main research contents are as follows: (1) the coupled mode theory, circuit theory and filter theory in WPT analysis are introduced. Combined with these three mainstream research and analysis methods, the optimal selection of WPT system is analyzed. (2) Frequency splitting in WPT system is introduced. Basic theories such as maximum efficiency criterion, maximum transmission power criterion and main coil parameters. (3) through circuit theory, combined with planar multi-load WPT system structure, the principle of load isolation of K converter is expounded in detail. A novel scalable planar wireless charging system with load isolation characteristics is proposed. By comparing with related research results, this paper expounds the advantages of the proposed system, and studies the three-dimensional multi-load WPT structure that can be applied to the system. (5) using numerical analysis and experimental methods, The load isolation scheme proposed in this paper is verified. Through the verification, the isolation effect of the load isolation scheme is well proved, and combined with the three-dimensional and planar WPT structures, the multiple devices are successfully charged at the same time and stably.
