摘要

提出一种由光伏供能的无线电力传输系统,其主要应用于电动汽车（EV）的恒流（CC）和恒压（CV）充电拓扑结构,只需调整继电器的开关状态,即可实现电感电容器-电感电容器（LCC-LCC）的CC输出和电感电容串联（LCC-S）的CV输出。与其他拓扑相比,无需冗余元件,且在工作过程中开关频率固定,具有较高的误差容限。所提出的拓扑结构还能实现双向CC和CV充电,而无需在一次侧和二次侧之间进行通信。为验证拓扑结构的有效性,在实验室中搭建6 kW样机,其最大有效率为94%。

Abstract

A wireless power transmission system powered by photovoltaics is proposed, which is mainly applied to the constant current （CC） and constant voltage （CV） charging topologies for electric vehicles （EVs）, and only needs to adjust the switching state of the relay to realize the CC output of inductive capacitor-inductive capacitor （LCC-LCC） and the CV output of inductive capacitor in series （LCC-S）. Compared with other topologies, no redundant components are required and the switching frequency is fixed during operation with high error tolerance. The proposed topology also enables bidirectional CC and CV charging without the need for communication between the primary and secondary sides. To verify the effectiveness of the topology, a 6 kW prototype is built in the laboratory with a maximum efficiency of 94%.
