基于拓扑切换的三线圈恒流恒压无线充电系统研究
Study on Three-coil CC and CV Wireless Charging System Based on Topology Switching
摘要
Abstract
Compared with the traditional plug-in charging system,the wireless power transfer( WPT )system has attracted more and more attention owing to its features which are safer,efficient,stable and convenient.Firstly,t a three-coil constant current( CC )and constant voltage( CV )wireless charging system based on topology switching is proposed,which can realize load-independent CC and CV charging output functions.The switching between CC and CV modes can be achieved by setting up two AC switches,and the system can be operated in a zero phase angle ( ZPA )state in both the CC and CV modes.Then,the AC switch is located on the receiving side of the system.The system does not need the assistance of additional wireless communication modules,which partly reduce the development cost of the system to a certain extent and avoids the instability caused by the possible interference of wireless communication.Finally,a validation test prototype was built with charging current of 3 A and charging voltage of 60 V,and its maximum power transmission efficiency can reach 92.9％.The experimental results basically agreed with the theoretical analysis,thus verifying the correctness and feasibility of the proposed system.关键词
