【摘要】：依据经皮能量传输理论,在罐状变压器的基础上利用有限元软件的磁路耦合功能进行仿真,从而计算经皮变压器铁芯和线圈的损耗和体积生热率。通过电磁场、流固场、温度场的多物理场耦合,对变压器进行温度场分析;提出通过监测次级线圈的温升值进而调整初级线圈的输入功率来实现稳定植入器件的吸收功率的方法,使植入器件功率稳定在32 W左右,大大提高了系统的稳定性和可靠性。
[Abstract]:Based on the theory of transdermal energy transfer, the magnetic circuit coupling function of finite element software is used to simulate the transdermal transformer based on the theory of transdermal energy transfer, so as to calculate the loss and volumetric heat generation rate of the core and coil of the transdermal transformer. Through the coupling of electromagnetic field, fluid-solid field and temperature field, the temperature field of transformer is analyzed. A method of stabilizing the absorption power of the implanted device by monitoring the temperature appreciation of the secondary coil and adjusting the input power of the primary coil is proposed. The power of the implanted device is stabilized at about 32 W, which greatly improves the stability and reliability of the system.
