摘　　要：介绍了体内微机电无线能量传输系统松耦合变压器特性,利用电磁场理论建立了该松耦合变压器的微分方程。采用有限元仿真软件Ansoft进行了仿真和分析,研究了初次级绕组位置、气隙、水平位移、铁芯和运行频率对初次级绕组电感和耦合性能的影响,为松耦合变压器的进一步设计和优化性能提供理论指导和参考。The characteristics of the loosely inductively coupling transformer for wireless power transmission of a MEMS inside human body were analyzed and mathematical differential equations as well as a numerical model were established, After simulations and detailed analysis of a transformer were carried out with Ansoft, the influences of the parameters, such as the position, gap horizontal displacement and ferrite core of the primary and secondary winding and working frequency, on the loosely transformer inductance and coupling performances were studied. Finally, some discussions and conclusions were given.
