Abstract

Megahertz (MHz) wireless power transfer (WPT) system is becoming a research trend because of its flexible spatial freedom. However, the high frequency circuit components limit the power level of MHz WPT system. Meanwhile, the actual application scenarios are changeable, so a single system design cannot meet the needs of multiple applications. In this paper, a design concept of modularized and reconfigurable MHz WPT is proposed to improve the system power level and design flexibility. With this method, the system requirements (power, efficiency and transfer distance) can be easily satisfied by the combination of modules. The design concept will be detailed explained through the analysis of the system architecture and the mathematical model. Finally, the influence of proximity effect and mutual inductance divergence achieves briefly analysis according to the simulation and test. And the modularized design concept is basically verified by the power and efficiency test results of four different combinations of UMs.

模块化和可重构无线电力传输:体系结构、建模和分析

兆赫(MHz)无线电力传输系统以其灵活的空间自由度正成为一个研究方向。然而，高频电路元件限制了MHz WPT系统的功率水平。同时，实际应用场景多变，单一的系统设计无法满足多种应用的需求。为了提高系统的功率水平和设计灵活性，本文提出了一种模块化和可重构的MHz WPT设计理念。通过模块的组合，可以很容易地满足系统的要求(功率、效率、传输距离)。通过对系统架构和数学模型的分析，详细阐述了系统的设计思想。最后，通过仿真和试验，对接近效应和互感散度的影响进行了简要分析。通过四种不同组合方式的功率和效率测试结果，基本验证了模块化的设计理念。
