【摘要】：负载的移除或投入使电场耦合无线电能传输(ECPT)系统的拓扑结构发生改变,通常会对开关管造成较大的冲击,使得系统无法正常工作。针对此问题,围绕基于E类变换器的ECPT系统的基本特性分析,利用负载移除前、后系统的等效电路形式基本一致的特点,给出实现系统负载软切换需具备的条件,并提出一种参数设计方法使得系统在固定的工作频率下即可实现负载的软切换。最后利用该方法得到一组参数,在Matlab仿真平台下构建系统的仿真模型并搭建实验电路,仿真和实验结果验证了该方法的可行性。系统在负载投入时为负载提供需要的功率并工作在稳定状态,系统效率达到85%以上,在负载移除后工作在低功耗状态。
[Abstract]:The removal or input of the load changes the topology of the electric-field coupled radio transmission (ECPT) system, which usually causes a great impact on the switch tube and makes the system unable to work properly. In order to solve this problem, the basic characteristics of ECPT system based on class E converter are analyzed. By using the characteristics of the equivalent circuit of the system before and after the load removal, the necessary conditions for realizing the soft switching of the system load are given. A parameter design method is proposed to enable the system to realize the soft switching of the load at a fixed working frequency. Finally, a set of parameters are obtained by using this method, and the simulation model of the system is constructed under the Matlab simulation platform and the experimental circuit is built. The simulation and experimental results verify the feasibility of the method. The system provides the required power for the load when the load is put in and works in a stable state. The system efficiency is more than 85%, and the system works in the low power state after the load is removed.
