AbstractThis paper is the continuation of Graph Sets Method (GSM) proposed in the companion paper Part I for deriving equations and analyzing Multi Coil (MC) Wireless Power Transfer (WPT) systems. After explaining GSM, categorizing WPT coils into three different types, and proposing some approximation techniques in Part I, this article, as the second part of this work, presents numerical simulations and experimental results for a three-coil MCWPT system similar to what is explained in Part I. The simulations are conducted in MATLAB/Simulink and ANSYS environments, and for the experimental model, three ferrite-less cylindrical coils are built and compensated to behave as Voltage Driven (VD), Current Driven (CD), and Passive (PS) coils respectively at the specific frequency of 200 kHz. After analyzing and comparing the simulation and experimental results, it is shown that GSM can be an effective and illustrative technique that facilitates comprehensive analysis of interactions amongst the coils and their characteristics, especially when WPT systems contain multiple coils.
