基于阻尼频率的感应电能传输系统耦合系数估计

This letter proposes a novel approach for estimating coupling coefficients in inductive power transfer systems based on damped frequencies. In systems incorporating a voltage load, disturbances can lead to current/power oscillations at a damped frequency due to poorly damping characteristics. By analyzing the damped frequency of the oscillating components of dc-side currents, the coupling coeffici...
