“…As with motor control, a combination of both methods has been proposed, originating SVM-DPC, which has been applied to a 3L-NPC [165]. Both VOC and SVM-DPC need only a multilevel modulation stage update, whereas DPC has been extended for multilevel converters in [166].…”

Multilevel converters have been under research and development for more than three decades and have found successful industrial application. However, this is still a technology under development, and many new contributions and new commercial topologies have been reported in the last few years. The aim of this paper is to group and review these recent contributions, in order to establish the current state of the art and trends of the technology, to provide readers with a comprehensive and insightful review of where multilevel converter technology stands and is heading. This paper first presents a brief overview of well-established multilevel converters strongly oriented to their current state in industrial applications to then center the discussion on the new converters that have made their way into the industry. In addition, new promising topologies are discussed. Recent advances made in modulation and control of multilevel converters are also addressed. A great part of this paper is devoted to show nontraditional applications powered by multilevel converters and how multilevel converters are becoming an enabling technology in many industrial sectors. Finally, some future trends and challenges in the further development of this technology are discussed to motivate future contributions that address open problems and explore new possibilities.

This paper is concerned with modeling and simulation of a wind energy system with different topologies for the power converters, namely a matrix converter and a multilevel converter. We use pulse modulation by space vector modulation associated with sliding mode for controlling the converters, and we introduce power factor control at the output of the converters. Finally, we present the electric behavior for the power and the current at the output of the converters.Index Terms--Modeling and simulation, power converters, wind energy.

“…Direct Power Control (DPC) is a well known efficient control strategy for electronic power converters where the instantaneous reactive power theory introduced by Akagi et al is used [26]. This strategy is based on the evaluation of the active and reactive instantaneous power errors values and the voltage vector position [11], [12] or on the Virtual-Flux vector position [13], [14] without any internal control loop for the currents. The main objective of basic DPC technique is to choose, through a Look Up Table (LUT), the best state of the power semiconductors among the possible states in order to achieve instantaneous active and reactive power tracking towards their references.…”

In this work, a Model Based Adaptive Direct Power Control (MB-ADPC) with constant switching frequency for Three-Phase Three-Level Neutral Point Clamped (3L-NPC) converters is proposed. The rectifier and inverter operation mode are used to illustrate the flexibility of the proposed MB-ADPC controller. The control design process is based on the continuous averaged model of the system. Depending on the operation mode different control objectives have to be guaranteed. The proposed controller ensures the voltage regulation of the dc-link capacitors for the rectifier operation mode and to achieve voltage balance in the dc-link capacitors and the active and reactive power tracking for the rectifier and inverter operation modes. In addition, adaptive techniques are used to avoid system parameters uncertainties as smoothing inductors and grid frequency values. This work shows that the application of advanced control strategies based on the system model allows enhancing the performance of the overall system. The details of the controllers design process and the experimental results using a 50 kVA Three-Phase Three-Level NPC prototype are presented in this paper validating the proposed controllers.
