摘要：
A rapid design approach to achieve the optimal efficiency in a magnetic resonant wireless power transfer (MR-WPT) system is presented. A concise design guideline is provided to determine the optimal efficiency condition and related coupling coefficients. Experimental validations are demonstrated by both simulation and measurement results of a 6.78 MHz MR-WPT system prototype with the maximum efficiency of 76.1% at a 50 mm distance between transmitter and receiver.
