System Identification and Tuning of Wireless Power Transfer Systems with Multiple Magnetically Coupled Resonators
Journal article, 2018
This identification procedure yields an accurate system model which we use to tune the four capacitance values to recover high system-performance and account for, e.g., manufacturing tolerances and coil displacement. For a prototype WPT system, we achieve 3.3 kW power transfer with 91 % system efficiency over an air-gap distance of approximately 20 cm.
