摘要：为了适应锂电池的恒流-恒压充电特性,避免过充欠充等问题,提出一种基于LCC-LCL/S拓扑的恒流-恒压自切换谐振式无线电能传输系统。该系统不涉及原、副边通信以及移相、调频等复杂的控制方式,仅通过控制副边的两个开关切换拓扑即可实现系统输出特性的切换,且充电完成后系统能自动切换至低功耗状态。首先,提出基于LCC-LCL/S的新型混合拓扑,根据单拓扑的等效互感电路分析其输出特性以及零相角特性;其次,基于理论推导与最大安全电流约束给出一套参数配置方法,为参数设计提供理论支撑;然后,考虑切换点负载阻值大小以及系统空载对输出稳定性的影响,分析实际中可能出现的负载开路与充电完成负载移除的特殊情况,验证系统的稳定性与安全性;最后,搭建仿真和实验平台,实现系统最大输出效率为88.6%的恒定输出及平滑切换,验证所提方法的有效性和正确性。
In order to adapt to the charging characteristics of lithium batteries and avoid overcharging or undercharging problems,a resonant wireless power transmission system based on LCC-LCL/S topology was proposed,featuring self-switching between constant current and constant voltage output modes.The system does not require sophisticated control methods such as primary and secondary side communication,phase shifting,or frequency modulation,and it can switch the output characteristics of the system only by controlling the two switches on the secondary side to switch the topology.Upon the completion of charging,the system can automatically switch to a low-power state.Firstly,a novel hybrid topology based on LCC-LCL/S was proposed,and its output characteristics and zero-phase-angle characteristics were analyzed according to the equivalent mutual inductance circuit of the topology;Secondly,a parameter configuration method was developed based on theoretical derivation and maximum safe current constraints,providing theoretical support for parameter design;Then,considering the impact of load resistance at the switching point and system no-load operation on output stability,practical cases such as load open-circuit and load removal after charge completion were analyzed to verify the system’s stability and safety;Finally,a simulation and experimental platform was built,achieving constant output and smooth switching with a maximum output efficiency of 88.6%,thereby verifying effectiveness and correctness of the proposed method.
