Two-Port Network Analysis of Equal Fractional-order Wireless Power Transfer Circuit

Wireless power transfer (WPT) has been widely employed in many applications. Its advantages have added more safety and ease in various medical, industrial, and electrical applications. This paper investigates the two-port network concept in the analysis of the fractional-Order WPT circuit. A general expression for the WPT efficiency as a function of two-port network parameters is derived. It is represented in terms of the transmission matrix parameters of a generalized Two-Port network. The analysis is performed on both Series-Series (SS) and Series-Parallel (SP) topologies. The best efficiency is then found by trying different values of frequency and load. The efficiency is simulated and investigated analytically and numerically on a SS and SP topology. In this paper, the SP topology's efficiency and performance are found to be better than the SS topology, applying equal fractional-order, which is in this paper equals 0.9. © 2020 IEEE.
