摘要
在用于视网膜植入物的无线功率传输转换器中，感应链路耦合系数的突然变化会导致向植入物提供过多的瞬态功率。这种能量的消散会增加眼睛的温度，从而伤害敏感的眼部组织。本文在COMSOL环境下，研究了新型FF类变换器作为频率为1 MHz的50 m W /5 V无线电力传输电路在视网膜植入物中的热性能，并与传统的e类变换器进行了比较。
Thermal Performance of Class- FF Converter Used for Wireless Power Transfer in Retinal Implants
In wireless power transfer converters used for retinal implants, a sudden change in coupling coefficient of the inductive link results in delivering excessive transient power to the implant. Dissipation of this power increases the eye temperature, which can hurt the sensitive eye tissues. In this paper, thermal performance of the new class- FF converter used as a 50 m W /5 V wireless power transfer circuit with the frequency of 1 MHz in retinal implants is studied and compared with the conventional class-E converter in COMSOL environment.
