Analysis of the Influence of the Skin Effect on the Efficiency and Power of the Receiver in the Periodic WPT System

The article shows an analysis of the influence skin effect on maximum efficiency and power a receiver in wireless transfer system (WPT). For this purpose, original solution WPT was used, which contained periodically arranged planar coils. results concern multi-variant system. geometry coils taken into account, i.e., size coils, number turns, as well distance between transmitting receiving calculations were carried out over frequency range 0.1–1 MHz. In order to analyse proposed system, two approaches used: analytical numerical. analyses appropriate selection load impedance obtain or receiver. analysis, each operating procedures examined. obtained numerical differed by no more than 0.45%, confirmed correctness model. Based results, it determined that greatest occurred at 1 Then, decreased 9%, while case average 25%. Detailed parameters, can also be important element design systems.
