Simulation and Experimental Based Analysis of the Power Factor in Phase-Angle-Controlled AC-AC Converter Types

Power electronics is a rapidly evolving field, driven by advancements in converter technology across a wide range of applications. However, the non-linear nature of these converters generates harmonics, adversely affecting their performance and power quality, particularly power factor. This study investigates the supply-side power factor characteristics of different AC voltage converter types that utilize phase-angle control methods. Simulation models for AC voltage converters are implemented in the MATLAB by utilizing Simulink along with the Sim Power Systems toolbox. A comprehensive analysis of power factors is conducted on both simulation models and experimental setups, and the results from simulations and experiments are compared to validate the findings.
