The paper considered the theoretical information of generators for several power sources, schematic their solutions, and the main disadvantages and advantages. A generator for 4 batteries based on field-effect transistors with optical galvanic isolation and a clock generator built on the basis of the Atmega328 microcontroller, which is part of the Arduino Uno device, was studied. The result of the study was the confirmation of the existence of the "Tesla-switch" effect. A program code was developed for the alternate switching of six transistor switches of the optical decoupling. The structural diagram of the device was studied, and the influence of the generator frequency and the consumed power of the load on the output parameters of the device were determined. The considered idea of energy saving and environmental friendliness of power supply systems is relevant, in particular in cases of blackouts.

The paper proposes electromagnetic field equations from the point of view of their adaptation to numerical methods. Maxwell's equations with partial derivatives are used, written concerning field vectors, which most fully reproduce the picture of physical processes in electrical engineering devices. The values of these vectors provide comprehensive information about the field at any spatio-temporal point. The concept of creating mathematical models of electrical devices adequate to physical processes has been developed. Mathematical transformations are carried out according to the rules of differential calculus. Dynamic processes in the elements of electrotechnical devices were analyzed using the apparatus of mathematical modeling. An algorithm for implementing differential equations with partial derivative numerical methods using computer simulation was implemented. The obtained results made it possible to understand the nature of electromagnetic phenomena in nonlinear media. The paper provides calculations of the field parameters in a flat ferromagnetic plate and the groove of the rotor of an electric machine.

“…The dynamics of the transformation of investment and innovation factors of international competitiveness prove that there is a global trend for the development of high-tech production, innovative capital and the environmental factor [13,14,15]. At the same time, the instability of the financial market and the strengthening of the protection of national producers often hinder the development of the country's competitiveness.…”

The purpose of this work is to study the quality of the innovation-investment component of the international competitiveness of EU countries and Ukraine, to reveal the potential of innovation-investment activity in ensuring the effectiveness of the national economy, as well as to substantiate the priority vectors of leveling external shocks and promoting economic growth in Ukraine. The work evaluates the quality of the innovation and investment component of the international competitiveness of Ukraine and its close neighbors - the countries of the Visegrad Group (Poland, the Czech Republic, Hungary and Slovakia) using econometric analysis; a multifactor economic-mathematical model was built, which determines the strength of the connection between indicators of innovation and investment activity in Ukraine and the main macroeconomic indicator - GDP; the European practice of developing strategic programs to increase the competitiveness of the country's economy was studied; strategic innovation and investment initiatives of Ukraine are substantiated. In addition, the article made a significant theoretical and practical contribution to solving the outlined problems. The results of the study revealed the main problems of the innovation-investment component of Ukraine's international competitiveness, as well as highlighted the potential prospects for its improvement, taking into account advanced European practices.
