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:Load-switched changes the topology of electric-field coupled power transfer (ECPT) system, usually causing dramatic impacts on the transistor and making the system cannot work properly. Focusing on the basic characteristics of the E-converter based ECPT system, this paper provides the condition of load soft-switched and proposes a parameter design method to achieve load soft-switched at the fixed operating frequency, where the same equivalent circuit of the system with load-switched is utilized. Thereafter, a set of parameters are obtained. Finally, the simulation and experimental prototypes are built. Both simulation and experimental results verify the proposed method. The system can provide the required power at the steady state with the efficiency over 85%, while it works at low power consumption after the load is removed.
