“…Power converters constitute an intermediate stage between the energy source and the end-users or load (e.g., consumers in residential or industrial spaces). Among the options for power converter topologies, matrix converters (MCs) have attracted particular attention because of several advantages, including reduced size, high efficiency and significant improvement in overall system reliability by elimination of failure-prone dc-link electrolytic capacitors [3]. Similarly, model predictive control represents a good alternative for the control of power electronic devices, with the advantages that it is easy and simple to implement, can be applied to a great variety of systems, offers simple treatment of constraints, and can deal with multi-variable systems and non-linearities [4].…”

Power electronic devices play an important role in energy conversion. Among the options, matrix converters, in combination with predictive control, represent a good alternative for the power conversion stage. Although several reviews have been undertaken on this topic, they have been conducted in a non-systematic manner, without indicating how the studies considered were chosen. This paper presents results from a systematic literature review on predictive control applied to matrix converters that included 142 primary papers, which were selected after applying a defined protocol with clear inclusion and exclusion criteria. The study provides a detailed classification of predictive control methods and strategies applied to different matrix converter topologies. Research findings require to be understood in combination to develop a common understanding of the topic and ensure that future research effort is based on solid premises. In light of this, this study identifies and characterizes different predictive control techniques and matrix converter topologies through systematic literature review. The results of the review indicate that interest in the area is increasing. A number of open questions in the field are discussed.

“…Matrix converter (MC) is a power electronic AC-to-AC converter without any DC storage element such as capacitor or inductor. 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].…”

Sparse matrix converter (SMC) is an indirect AC-to-AC power electronic converter that has a fictitious DC link between rectification and inversion stages in which neither a capacitor nor an inductor, as the storage element, is utilized. Due to this advantage, SMC is used in AC drives, marine thrust systems, aerospace industry, as well as in wind energy applications. On the other hand, permanent magnet synchronous generator (PMSG) is competitive in wind turbine applications due to their prominent features. In this work, a fuzzy fractional-order PID (FFOPID) controller is designed for a PMSG based wind energy conversion system (WECS) which employs a three-phase three-level SMC. The FFOPID controller is chosen to combine the salient features of the fractional-order calculus and fuzzy logic operations to enhance the dynamic response of classical PID controller with fixed gains. The simulation results taken under different case studies are analyzed in detail, which demonstrate the superiority of the designed FFOPID controller over classical PID control approach in tracking d- and q-axis current references of the SMC at the output. With the designed control approach, the smooth control of the real and reactive power injections into the grid from the WECS are ensured with acceptable transient response.

“…The series connection of the input AC matrix converters, with small film capacitors voltage dividers, eases semiconductor voltage blocking capability, as STs may interface medium voltage grids to low voltage AC grids. Besides, the matrix converter‐based ST can also be applied to smart grids, providing multiple ports for the demand of particular loads [19]. Reference [20] shows a comprehensive comparison of a matrix converter and back‐to‐back converter.…”

A novel matrix converter‐based topology to be applied in smart transformers (STs) is proposed, based on the concept of multiple modularity. To replace the conventional ST topology obtained by H‐bridge modules including DC electrolytic capacitors, the proposed ST topology uses two kinds of matrix modules to provide flexibility in the AC–AC structures to build complex ST. Fewer power semiconductor devices are used in each module to reduce the costs. The AC–AC matrix converters and the high‐frequency transformers eliminate electrolytic capacitors, enhancing ST reliability and power density. The modulation method for the proposed ST structure needs suited carrier waves and switching processes. The half‐Venturini modulation method shows several switching sequences leading to voltage imbalances in the input film capacitor divider. Therefore, the paper investigates and analyses the influence of switching sequences on the capacitor voltages in detail. The results show that the different switching sequences will cause different currents flowing into capacitors, leading to different results in capacitor voltages. Based on the analysis, proper modulations are recommended for the proposed topology. In order to verify the feasibility of the proposed topology as well as the correctness of the analysis on modulations, simulations and hardware‐in‐loop experiments are carried out. It is found that the modularity concept is feasible, and a suitable modulation sequence was developed to balance the input capacitors voltages.
