特定输出功率下表皮能量传输系统优化设计

摘要

经表皮能量传输系统通过空气间隙中的耦合磁场,将能量由体外一次能量源耦合传输到体内植入的能量二次能量接收端.针对不同的应用情况,提出了指定输出功率下,对系统进行优化的方法.优化理论以传输效率为目标函数,一次二次能量线圈为设计变量,以频率分叉现象和元器件的最大峰值电流和电压作为约束条件.最后使用MATLAB/Simulink对分析结果进行验证.%Transcutaneous energy transmission ( TET) systems are designed to transfer power from an in vitro primary device to in vivo implantable secondary via magnetic coupling. This paper proposes an optimization method to optimal a system with given output power to meet different practical application. The transmission efficiency is the objective function; primary and secondary coils'inductances are design variables; constraints are based on bifurcation phenomenon and components' peak over - voltage and peak withstand current. At last MATLAB/ SIMULINK was used to verify the analytical results.
