Modulation Methods for Direct and Indirect Matrix Converters: A Review

Abstract

Matrix converters (MCs) allow the implementation of single-stage AC/AC power conversion systems (PCS) with inherent bidirectional power flow capability. By avoiding the typical DC-link capacitor, MCs have the potential to achieve higher power density with a more reliable operation and less maintenance when compared with conventional two-stage AC/DC/AC PCS. For these reasons, matrix converters have been receiving significant attention from the academic sector but have not yet been implemented on a large industrial scale. This article reviews the Direct Matrix Converter (DMC) and the Indirect Matrix Converter (IMC) along with the respective actual and most important modulation methods. Simulation results are provided to validate the theoretical analysis and to get a deep insight about the implementation of space vector modulation (SVM) and respective switching pattern generator.

Improvement of Sliding Mode Control Strategy Founded on Cascaded Doubly Fed Induction Generator Powered by a Matrix Converter

“…The MC is represented as a two-level converter connected by an imaginary DC link in order to employ the SVPWM: the first level acts as an input rectifier with the current link and the second level acts as an output voltage source inverter [17,26]. For further information, the interested reader is directed to [2,[21][22][23][24][25][26][27]. Power circuit topology of the 3×3 IMC.…”

Fuzzy Fractional-Order PID Control for PMSG Based Wind Energy Conversion System with Sparse Matrix Converter Topology

“…Tis adaptation reduces converter size, upsurges converter reliability, as well as provides four-quadrant operation [1][2][3]. Due to these salient features, MCs have been used in many applications such as AC drives, marine propulsion systems, aerospace industry, and renewable energy systems [4]. Recently, MCs have gained increased interest in wind energy applications [5].…”

“…On the other hand, sparse MC (SMC) is a member of MC family, in which indirect power conversion is realized using rectifer and inverter stages separated by a fctious DC link without any DC storage element [9]. Te control complexity of the power semiconductor switches in SMC is a challenging task, since switching synchronization between rectifer and inverter stages is needed [4]. SMC has also found application areas in WECS.…”

Research on an Optimized Overmodulation Strategy Based on Rectifier of Indirect Space Vector of Matrix Converter

“…Matrix converter (MC) achieves direct AC-AC power conversion without intermediate energy storage elements. The MC features high power density and high efficiency [1][2][3], which has been demonstrated from both academia and industry. Therefore, it has been widely considered a promising topology to the widely used AC-DC-AC converter and back-to-back PWM converter.…”
