一种通过测量发射端电流估计IPT系统耦合系数和输出电压的双频调谐方法

A dual-frequency tuning method of inductive power transfer (IPT) system is proposed to estimate the coupling coefficient and output voltage from the transmitter (Tx) during power transfer without using an additional communication channel. The Tx is designed to resonate at both the fundamental and seventh-order frequencies of a square wave voltage. The power receiver (Rx) coil is also tuned to main...
