Performance Analysis of Single Phase AC-AC Voltage Converter for Compensation of Voltage Issues in Power Distribution System

Abstract

The power quality of the power distribution system is highly concerned with the use of renewable sources, solid-state electronic devices, and power electronic processors. This results in voltage fluctuations, voltage sag, and swell issues. The voltage source converter (dc-to-ac) can resolve these issues but there is a problem with high rating storage devices. The Dual converter (ac- to-dc) will be useful for energy-storing devices but due to complex circuit arrangement and high conversion losses, this converter is not favorable. The direct AC-AC voltage converter is a matter of research due to simple conversion. This paper presents the performance analysis of a single-phase ac-to-ac voltage converter operating in inverting and non-inverting modes with no current commutation problems. The performance analysis of the proposed converter is been done in MATLAB/Simulink 2019b. Keywords-Voltage sag and swell, voltage control, inverting mode, non-inverting mode, power distribution system
