Validation of a reflected-impedance design method for wireless power transfer applications

Abstract

This paper proposes a simplified method for designing four-coil resonant wireless power transfer (WPT) networks by sequential application of impedance reflection through mutual inductances. Experimental validation is presented, and accuracy and limitations of the method are described. The method appears useful for first-pass (approximate) design, but accurate simulation requires consideration of mutual inductances of non-adjacent coils.
