Development and computer simulation of AC voltage regulator
Incoming article date: 18.03.2019Development of electric energy converters with high energy characteristics is an important scientific and technical task. The solution of this problem is impossible without the use of modern methods of computer modeling. To improve the quality of electricity, filter-compensating devices are used. Develop converters with good energy performance. In this paper, we developed a computer model and circuit of the AC voltage regulator with high-frequency pulse modulation of the output voltage. Methods of digital signal processing and computer simulation are used. In the environment of the software product MATLAB, a program synthesizing the form of voltage at the output of the AC voltage regulator. The program uses a variety of algorithms to control the power keys of the AC voltage regulator. The results of harmonic analysis of the output voltage of the regulator are presented. The study of the AC voltage regulator circuit is performed in the environment of the ORCAD software product. The work of the scheme on the active-inductive load is considered. Electromagnetic processes occurring in the circuit of the AC voltage regulator are investigated. The optimization of the scheme elements is performed. Time diagrams of currents and voltages are obtained. The results of computer simulation can be used in the development of electrical energy converters for electrochemical and electro thermal production.
