Magnetic transcutaneous coupling is frequently used for power and data transfer to implanted electronic devices. The paper describes a transmitter/coil driver based on the class E topology. The development of a 'high-Q approximation' simplifies the design procedure. A method of data modulation using synchronous frequency shifting is described. The class E circuit shows great promise, especially for circuits with unusually low coefficients of coupling. Transmitter coil currents of several amperes, at radio frequencies, with relatively low active device power dissipation, can easily be obtained.
磁经皮耦合常用于向植入式电子设备进行能量和数据传输。本文描述了一种基于E类拓扑的发射器/线圈驱动器。“高Q近似”的发展简化了设计过程。描述了一种使用同步频移的数据调制方法。E类电路显示出巨大的潜力，特别是对于耦合系数异常低的电路。在射频下，能够轻松获得数安培的发射器线圈电流，且有源器件功耗相对较低。
