Abstract

This paper proposes a series active filter and shunt active filter to minimize the power quality impact present in matrix converters instead of passive filter. A matrix converter produces significant harmonics and nonstandard frequency components into load. The proposed system compensates the sag and swell problems efficiently in matrix converter. The proposed system has been tested and validated on the matrix converter using MATLAB/Simulink software. Simulated results confirm that the active power filters can maintain high performance for matrix converter.

Highlights

Power quality is a set of limits or conditions of electrical properties that allows electrical devices to function in their planned manner without loss of performance
An optimized design of the matrix converter input filter is a quite difficult task, since it relies on a system level approach, and in the light of the new coming harmonic and EMI reduction standards it can be considered as an outstanding issue
The series active filter control system for voltage type harmonic source compensation is proposed in this matrix converter

Summary

Introduction

Power quality is a set of limits or conditions of electrical properties that allows electrical devices to function in their planned manner without loss of performance. Matrix converter has several advantages over traditional rectifier-inverter type power frequency converters. It provides sinusoidal input and output waveforms. It has inherent bi-directional energy flow capability; the input power factor can be fully controlled. In spite of the advantages the matrix converter has some disadvantages It has a maximum input-output voltage transfer ratio limited up to 87% for a sinusoidal input and output waveforms. It requires more semiconductor devices than a conventional AC-AC indirect power frequency converter, since no monolithic bidirectional switches exist and the discrete unidirectional devices are arranged.
