A Comparative Performance Analysis of Wireless Power Transfer with Parametric Simulation Approach

Abstract

This paper presents a parametric optimization and normalization approach for coreless Resonant Inductive Coupling Wireless Power Transfer (RIC-WPT) systems. The used system is based on a series–series (SS) compensated circuit via flat spiral coils. Moreover, the recommended approach system finds optimum capacitor values for the best efficiency point where the RIC-WPT system operates. Flat spiral three-dimensional (3D) coils are modelled and parametric analysed with different air gaps in ANSYS-Electronics-Maxwell software which is based on the Finite Element Method (FEM). Then power electronics circuit with a full-bridge inverter is designed in Ansys/Simplorer software. The coils and the power electronics circuit are co-simulated with parametric values. Thus, as a result of parametric simulation studies, the most efficient version of a Wireless Power Transfer (WPT) system structure is proposed with the design and normalized power electronics elements that can be physically applied for the chosen operating frequency value. As a result of the simulation studies, power transmission is realized with an efficiency of approximately 74.31% while the distance between the coils was 200 mm. Furthermore, useful information for WPT designs is been obtained thanks to co-simulation studies by changing power electronics circuit parameters and electromagnetic modelling parameters.

Enhancing electric vehicle charging performance through series-series topology resonance-coupled wireless power transfer

“…The resonance inductive coupling WPT system utilizes capacitors and coils during resonance to efficiently transmit power wirelessly [ 32 ]. At resonance, inductive reactance (XL) equals capacitive reactance (XC), allowing for maximum current flow, defined by the resonant frequency (ω 0 ) determined by the following equation: …”
