Simulation of Electromagnetic Processes in the Filter-Compensator Device as Part of the Charging System of the Capacitive Storage

Abstract

The relevance Secondary power supplies, frequency converters, and inverters are actively used in modern rapidly developing power engineering. The trend towards a decrease in the weight and size of devices and an increase in their power explains the need to use pulse modes of electrical energy converters. The oscillatory circuits of resonant inverters contain elements such as an inductor and a capacitor, i.e. electromagnetic elements, as a rule, constituting up to 85–90 % of the mass and dimensions of secondary power supplies. The main technical means of reducing the mass and dimensions of electromagnetic elements are increasing the conversion frequency and functional integration. Resonant modes of operation of inverters during switching can reduce interference and losses. Aim of research This article discusses the development of an efficient capacitive storage charging system and simulation of electromagnetic processes in a filtercompensating device as part of an efficient capacitive storage charging system. The main task is to develop an efficient capacitive storage charging system. Research methods Research methods. In this study, the following methods were used: the study of scientific literature and computer simulation in the Matlab environment. Results The authors have developed a computer model in MatLab of a capacitive storage charging system based on a half-bridge circuit of an inductivecapacitive converter. A multifunctional integrated electromagnetic component (MIEC) is used as a pre-absorber. Investigations of voltage levels at various points of the four-terminal network have been carried out. The voltage on the plates and capacitance MIEC was determined. The voltage in the diagonals of the inverter was measured to find the maximum voltage. Because of computer modeling and experimental research, graphs of voltages on the elements of the half-bridge circuit of the capacitive storage charging system were obtained. The developed computer model will allow the investigation of various modes of operation of a secondary power source based on the proposed component in high-voltage charging systems for energy storage devices. The developed model allows you to reduce the financial costs of experimental research. Also, this model allows you to explore more complex systems based on MIEC, which have different properties and indicators.
