一种利用谐波电流估计耦合系数的宽充电范围无线电能传输控制系统

In the wireless power transfer (WPT) control system, estimating the coupling coefficient (k) is an essential step to achieving optimal control over a wide charging range. The estimate required signal of the traditional WPT system is mainly the currentand voltage generated by fundamental. It requires many parameters and complex calculations to estimate k by analyzing these electrical signals, which...
