Two-level Iterative Algorithm for Solving State Equations of the WPT System

An efficient two-level iterative algorithm for solving the state equations (nonlinear mode analysis) of the wireless power transmission (WPT) system is proposed. The conditions of its convergence are investigated. The possibility of increasing the efficiency of the iterative process of the upper level due to the use of specific properties of the linear subscheme of the WPT system, which are inherent in certain external influences of certain types of antennas with nonlinear elements (ANE), in particular rectenna.
