ACCURATE CALCULATION OF THE POWER TRANSFER AND EFFICIENCY IN RESONATOR ARRAYS FOR INDUCTIVE POWER TRANSFER [PDF]
Progress In Electromagnetics Research B, 2019 This paper studies the power transfer characteristics of a resonator array for inductive power transfer by means of the accurate analytical solution of its circuit model. Through the mathematical inversion of a tridiagonal matrix, it is possible to obtain closed-form expressions for the current in each resonator and consequently expressions for the ...
