该论文提出了一种用于生物植入设备的无线功率传输系统，通过使用初级均衡器来扩展耦合和负载范围，解决了因线圈耦合变化和负载变化导致的整流器输出电压不稳定的问题。
Wireless power transfer (WPT) in the range of 10 to 100mW [1] is widely used in implantable medical devices (IMDs) to eliminate the use of a battery. Due to load and coupling variations, the output voltage of the rectifier VOUT is not steady. In [1-2], a 1X/2X reconfigurable rectifier was reported to uphold VOUT when the coupling coils move apart. In [3], VOUT is regulated by the transmitter with feedback through a wire, which defeats the purpose of WPT. In [4], VOUT is regulated by a resonant regulating rectifier as well as an MCU-controlled transmitter with feedback still through a wire. In [5], a reconfigurable resonant regulating (R3) rectifier is reported for VOUT regulation, but the load and coupling ranges are limited. In the R3 rectifier, the 1X/2X rectifier works as a bridge rectifier in 1X mode with VOUT equal to V1X, and as a voltage doubler in 2X mode with VOUT equal to V2X as shown by the dash lines in the HSPICE simulated
