Abstract

The study of Current Source Matrix Converter (CSMC) static properties using the averaged state-space method for two modulation strategies Venturini and Space Vector Modulation (SVM) is the subject of this article. The converter properties for both modulation strategies have been examined and compared. The modeling approach based on the averaged state space method presented in this paper is relatively simple and requires only a small number of mathematical transformations. The averaged set equation is obtained directly from the three-phase schematic circuit, taking into account the sequences of switching patterns and modulation strategies. All the obtained results have confirmed that CSMC has some interesting properties, such as buck–boost output voltage regulation unlike the classic Matrix Converter (MC), in which the maximum voltage gain is 0.866.

Highlights

  • Frequency converters (FC) are power electronics that convert alternating current (AC) electrical energy with specified parameters into alternating current electrical energy with desired parameters [1].One of the most desirable features of an FC is the generation of output voltage or current with arbitrary amplitude and frequency

  • Source Matrix Converter (VSMC)—Figure 1a [10,11]. This type of MC configuration has a significant disadvantage in the form of low output voltage gain, which reaches a maximum value of KU max = 0.866, for undistorted load current [7,11]

  • Only fundamental components of input/output voltages frequency are taking into account without higher harmonic components and power losses which are in the experimental setup

Summary

Introduction

Frequency converters (FC) are power electronics that convert alternating current (AC) electrical energy with specified parameters into alternating current electrical energy with desired parameters [1]. Source Matrix Converter (VSMC)—Figure 1a [10,11] This type of MC configuration has a significant disadvantage in the form of low output voltage gain, which reaches a maximum value of KU max = 0.866, for undistorted load current [7,11]. MC fed a current source gives the possibility of increasing the voltage on the load terminals The disadvantages of this solution are the need to use large input chokes and the dependence of the voltage gain characteristic on the load change [11]. The averaged state space method deserves special mention In this method, only fundamental components of input/output voltages frequency are taking into account without higher harmonic components and power losses which are in the experimental setup.
