Abstract
This article aims to present a comprehensive approach with corresponding software that uses index matrices. They have been developed by the authors for an automated model-based design. One of the main goals of this paper is to propose a simple model solving technique for powering electronic devices (particularly, for all subsystems: power supplies, static power converters, electric filters, electrical loads, control systems, etc.). Index matrices, which contain first-order discrete dynamical system parameters, with real numbers as elements, are constructed in order so that voltages, amperages, and discrete values can be calculated. Simulations on a three-phase converter, as well as simulations on buck and boost DC-DC converters with PI controllers, are presented. The function of the proposed software (with examples on the aforementioned devices) is considered, and diagrams of its basic programming classes are shown. The latter draws electronic schemes and their respective graphics, and provides important characteristics. Simulink is used to verify results. Advantages of the proposed approach are a higher speed of calculations (compared to Simulink, due to a lack of differential equations) and a simpler handling of various electronic components. Additionally, a computational scalability is demonstrated.

Summary
Academic Editors: Bor-Ren Lin and Techniques of solving differential equations solving are widely applied in software for model-based design of real-life systems. Power electronic components and devices are modeled in the libraries of one of the most popular graphical programming environments, Simulink, which uses a large number of simulation parameters and model solving modes [1,2]. Many classes of dynamical systems can be represented by differential equations. Software implementations (see [5,6]) are useful with changing dependencies, because many estimations cannot be performed in this case; generally, power converters can be modeled with straightforward algorithms so that suitable simulations (based on non-constant matrices) can be performed [7,8,9]
