The matrix converter is an array of controlled semiconductor switches that connects directly the three-phase source to the three-phase load. This converter has several attractive features that have been investigated in the last two decades. In the last few years, an increase in research work has been observed, bringing this topology closer to the industrial application. This paper presents the state-of-the-art view in the development of this converter, starting with a brief historical review. An important part of the paper is dedicated to a discussion of the most important modulation and control strategies developed recently. Special attention is given to present modern methods developed to solve the commutation problem. Some new arrays of power bidirectional switches integrated in a single module are also presented. Finally, this paper includes some practical issues related to the practical application of this technology, like overvoltage protection, use of filters, and ride-through capability.

“…Schuster presented in 1998 a protection concept for MCs without reactive clamp elements for a motor drive system using varistors only (134) . An extended protection concept was proposed by Mahlein and Braun in 2000 based on varistors and suppressor diodes (135) that allows the removal of the standard diode clamp circuit. Various techniques to reduce the complexity of the protection circuits in CMCs and IMCs were suggested and investigated by Klumpner in 2005 including a protection concept for the IMC topology with only six diodes in the clamp circuit using standard half-bridge inverter modules (136) .…”

The Matrix Converter (MC) evolved from the forced commutated cycloconverters and has been extensively investigated for more than thirty years. In this publication, the milestones in research on MCs in academia and industry are reviewed and presented chronologically and thematically ordered. The major contributions in the fundamental topic areas such as the development of the topology, topological extensions, commutation, modulation, loss calculation, control, or filtering and EMC are compiled and then expanded with examples of the latest activities in the corresponding field of research. In addition, an overview of the publicly reported research on MCs in industry is provided and the development of the commercialized MCs is briefly summarized. This review concludes with a brief comparison of the MC with the voltage source converter and a discussion of the current status of the MC technology and its future potential.

A matrix converter without diode clamped over-voltage protection

Abstract: In this paper the design and testing of a new protection strategy for a matrix converter feeding an induction motor is described. The new protection strategy with excellent over-voltage protection allows to remove the large and expensive diode clamp.
