“…The MC family is still categorized as a laboratory AC/DC driver with little reliable potential for industrial use [6,7] because of the control complexity [8], sensitivity in the face of abnormal input [9], limitation of the voltage transfer ratio up to 86.6% [10], and excess semiconductor switches [11]. These are the most critical obstacles to overcome, and, hence, solutions would be welcomed by manufacturers and industrial developers.…”

A rotational d-q current control scheme based on a Particle Swarm OptimizationProportional-Integral (PSO-PI) controller, is used to drive an induction motor (IM) through an Ultra Sparse Z-source Matrix Converter (USZSMC). To minimize the overall size of the system, the lowest feasible values of Z-source elements are calculated by considering the both timing and aspects of the circuit. A meta-heuristic method is integrated to the control system in order to find optimal coefficient values in a single multimodal problem. Henceforth, the effect of all coefficients in minimizing the total harmonic distortion (THD) and balancing the stator current are considered simultaneously. Through changing the reference point of magnitude or frequency, the modulation index can be automatically adjusted and respond to changes without heavy computational cost. The focus of this research is on a reliable and lightweight system with low computational resources. The proposed scheme is validated through both simulation and experimental results.

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.

“…These topologies have a reduced number of input switches but they have the same functionality of the standard indirect matrix converter. The ultrasparse matrix converter is the simplest one and consists of only nine electronics switches and 18 diodes [17]. Finally, the technology of matrix converter has been applied to ac-dc conversion with interesting results in [18]- [21].…”

Passive three-phase rectifier circuits are very popular for ac-dc power conversion. However, they do not have the capability to reverse the power flow, which is demanded by some recent potential smart-grid applications, such as vehicle-togrid (V2G) power transfer. This paper compares two structures of reversible battery chargers, i.e., an interleaved dc-dc converter fed by a three-phase power factor corrector rectifier and a threephase ac-dc matrix converter, which may be suitable for plug-in electric vehicles. The comparison aims to estimate the power losses, the power capability and the size of the converters under common requirements.Keywords-battery charger, plug-in electric vehicle, ac-dc matrix converter, interleaved dc-dc converter, PFC.
