AbstractANSYS Q3D Extractor tool (AQ3DE), using the quasi-static solvers (method of moments, integral equations and FEMs), is very efficient for computing and simulating two- and three-dimensional electromagnetic field. This simulation is used to extract parameters of interest, such as: resistance (R), conductance (G), self-inductance (L), mutual inductance (M) and capacitance (C). These parameters can be further used to optimize and to obtain automatically the design of a wireless power transfer systems (WPTS). The resulting matrices allow the generation of new matrices for any selected parameters. To complete the analysis, the model which is computed will be exported as an equivalent circuit. In this paper, starting from a given WPTS, using AQ3DE tool, the parameters of interest (R, G, L, M, C) were automatically calculated, and the SPICE equivalent circuit was obtained. The analysis was performed for two different distances between the emitter and the receiver. The electrical circuit theory was used for the system analysis of magnetically coupled coil (MCC) system. Starting from the parameters extracted by the AQ3DE tool, the performance of the WPTS has been analysed both in time and frequency domain.

A method for modeling and printed circuit board layout in the form of a 3D model in one of the digital solutions designed for this task, Altium Designer, is proposed. The practical significance of the work is the study of the basic software libraries in terms of their creation, filling and application when working with the project, as well as of the algorithm for constructing an electrical circuit in the Altium Designer program, layout and design of the simplest circuit on the board. In the course of the work, the algorithm and rules for creating a library of three-dimensional models of components, a library containing conditional graphic designations of the corresponding components, a schematic diagram of the device, a three-dimensional model of the board and the construction of conducting tracks on it are described. The components and circuits used in the work are publicly available on the Internet, which allows anyone to work over the entire algorithm for studying and honing the skills of designing printed circuit boards, both by students studying at a higher educational institution and by fully-fledged specialists. This work can be used not only for teaching students in the field of electronic device development in terms of their design and for organizing laboratory work, but also for creating and designing real devices both in production and within a higher educational institution, for example, for creating a laboratory bench. The introduction and study of this software is carried out at the Department of Radio-Electronic Systems and Complexes of one of the leading engineering universities of the Russian Federation — the Bauman Moscow State Technical University.

This article presents a method for analysis of the low-power periodic Wireless Power Transfer (WPT) system, using field and circuit models. A three-dimensional numerical model of multi-segment charging system, with periodic boundary conditions and current sheet approximation was solved by using the finite element method (FEM) and discussed. An equivalent circuit model of periodic WPT system was proposed, and required lumped parameters were obtained, utilizing analytical formulae. Mathematical formulations were complemented by analysis of some geometrical variants, where transmitting and receiving coils with different sizes and numbers of turns were considered. The results indicated that the proposed circuit model was able to achieve similar accuracy as the numerical model. However, the complexity of model and analysis were significantly reduced.
