Multilevel converters (MLCs) have emerged as standard power electronic converters for medium voltage high power industrial applications. Owing to dominating device switching losses in high power applications, it is preferable to use low device switching frequency (LDSF) modulation techniques. Then, it is possible to achieve higher device utilization, higher converter efficiency and reduced cooling requirements. However, there exists a trade-off between device switching frequency and harmonic distortion of converter output currents. Therefore, the main challenge for LDSF modulation techniques is to minimize the harmonic distortion of output currents. The goal of this paper is to provide a review of various LDSF modulation techniques proposed in the literature and also discuss in detail about one of the the emerging LDSF control techniques known as synchronous optimal pulsewidth modulation. Finally, challenges to LDSF modulation techniques for emerging multilevel topologies and future trends in applications of MLCs are discussed to motivate further research, to enhance proposed LDSF techniques and to explore for new alternatives.

“…This generates a larger ripple in the system waveforms, which in turn requires an increased (and variable) switching frequency in comparison to other control solutions. Several solutions are proposed in literature including modifications to the of FCS-MPC pulse pattern [14] in order to include improvement to the vector sequence [15], introduce a modulation scheme [16]- [18], or increase the MPC prediction horizon [19]- [22]. In [16] an analytical solution to the switching time calculation is provided, whilst in [17], [18] a Space Vector Modulation technique (SVM) is applied to the MPC current control of a six-phase inverter to feed an Asymmetrical Dual Three-Phase Induction Machine.…”

Model predictive control (MPC) has a number of desirable attributes which are difficult to achieve with classical converter control techniques. Unfortunately, the nature of power electronics imposes restriction to the method, as a result of the limited number of available converter states. This, combined with the spread spectrum nature of harmonics inherent with the strategy, complicates further design. This paper presents a method for removing this characteristic without compromising the desirable functionality of predictive control. The method, named modulated MPC, is applied to a two-level three-phase converter and compared with a number of similar approaches. Experimental results are used to support theoretical analysis and simulation studies

One of the main issues with Model Predictive Control (MPC) applied to Power ElectronicsConverters is the ability to select only one output voltage vector which is applied during the whole sampling period. Such mode of operation requires, in order to improve the harmonic content, an increasing of the converter switching frequency which is variable depending on the operating conditions. In order to overcome these issues, whilst preserving all the advantages of MPC, this paper presents a novel Modulated Model Predictive Control, with the aim of obtaining a modulated waveform at the output of the converter without implementing an explicit modulation scheme. The proposed control technique is applied to the current control of a 2-Level, 3-Phase Active Rectifier, validated through simulation and experimental testing and compared to a traditional Model Predictive Control.
