Abstract

This study explores the enhancement of power quality in AC-AC direct converters through the integration of hybrid filters. AC-AC direct converters play a crucial role in various applications, including motor drives and renewable energy systems. However, they often suffer from power quality issues such as harmonic distortion and voltage fluctuations. Hybrid filters offer a promising solution by combining passive and active filtering techniques to mitigate these issues effectively. The historical evolution of matrix converters provides valuable insights into the development of AC-AC direct converters. Control strategies based on vector space modulation (SVM) and pulse-width modulation (PWM) techniques are investigated to optimize the performance of hybrid filters. Additionally, the implementation of hybrid filters in AC-AC direct converters is analyzed to achieve improved power quality and system stability. Overall, this research contributes to advancing the understanding and application of hybrid filters for enhancing the power quality of AC-AC direct converters. Abstract ok
