磁性的经皮连接器通常用来为植入的电子设备进行电源与数据传输。现在研制的微型植入物非常微小,我们可用皮下注射针将它们注入皮下。这种植入物的研制需要一种高效的磁性经皮连接器。本文论述了基于E级拓扑结构(Class E topology)的多频率发射机的线圈激励器,同时还阐述了一种简化设计过程的高Q值逼近(high-Q approximation)的研制方法。本文还论述了利用同步频率转换补偿发射机和接收机频率变化的闭环控制器及数据调整的方法。这种闭环的E级回路显示了它可喜 Magnetic transcutaneous connectors are commonly used to power and data the implanted electronic devices. Micro implants now being developed are tiny, and we can inject them subcutaneously with a hypodermic needle. The development of such implants requires an efficient magnetic transdermal connector. This paper discusses the coil actuators of multi-frequency transmitters based on the Class E topology and describes a method of high-Q approximation that simplifies the design process. This article also discusses the use of synchronous frequency conversion to compensate for transmitter and receiver frequency changes closed-loop controller and data adjustment method. This closed-loop E-class loop shows its welcome
