磁谐振无线传能的高性能体内接收线圈设计OA北大核心CSTPCD
Design of high-performance receiver coil for transcutaneously magnetically coupled resonance wireless power transfer
针对植入式装置的经皮无线能量传输中,体内接收小线圈品质因数低、自谐振频率高且难以与体外线圈匹配共振的问题,提出采用多子线圈串接构建空心体内能量接收线圈兼作植入电路的封装,并对子线圈中外径26 mm的印刷平面螺旋线圈(P-PSC)进行优化设计.在选定基材、基板厚度和线厚的基础上,采用部分元等效电路法仿真计算P-PSC的自谐振频率和品质因数,分析内半径、匝数及线宽线距比的影响,优选得到低剖面、高性能P-PSC的设计参数.测得双层P-PSC的自谐振频率…查看全部>>
Aiming at the problem of low quality factor,high self-resonant frequency of the small receiver coils inside the body,and the difficulty in matching the resonance with the external coils in transcutaneously wireless power transfer for implanted devices,the use of multiple sub-coils connected in series to construct the receiver coil that also served as the case of the implanted circuit was proposed,and the printed planar spiral coil(P-PSC)with an outer diamete…查看全部>>
