| Abstract [eng] |
This master thesis investigates the development of an AC voltage regulator based on the AC-AC buck-boost converter topology, aiming to overcome the limitations of current voltage regulation techniques in AC power systems. The theoretical part provides an overview of autotransformers and transformer tap changing voltage regulation, voltage sags, and dynamic control, while exploring various AC/AC Buck-Boost designs and their characteristics. The practical part involves the design, simulation, and analysis of the AC voltage regulator, followed by the assembly and testing of a physical prototype. The conclusions drawn indicate that the AC-AC buck-boost converter offers an efficient and compact solution for AC voltage regulation, and the proposed regulator demonstrates satisfactory performance. Recommendations for future research include optimization of the regulator, cost reduction, and economic feasibility analysis to ensure market viability. Overall, this work contributes to advancing AC voltage regulation and offers insights for practical implementation. Thesis consists of: 37 pages of text without appendixes, 25 figures, 2 tables and 19 bibliographical entries. |
