“…For direct MPC with programmed PWM, however, even though the switching frequency is constant-and as low as a few hundred Hz-it is decoupled from the sampling interval since such methods do not feature a modulation cycle of fixed length. In these methods, T s is set as small possible-in the range of a few tens of microseconds-in order to avoid unnecessarily big deviations from the offline computed switching patterns as well as to provide the controller with a high degree of robustness to disturbances and system nonidealities [79], [80], [82], [83]. In doing so, both high-bandwidth controllers result and the applied switch positions manage to produce current harmonic distortions that are close to their minimum values.…”

Model predictive control (MPC) has established itself as a promising control methodology in power electronics. This survey paper highlights the most relevant MPC techniques for power electronic systems. These can be classified into two major groups, namely, MPC without modulator, referred to as direct MPC, and MPC with a subsequent modulation stage, known as indirect MPC. Design choices and parameters that affect the system performance, closed-loop stability and controller robustness are discussed. Moreover, solvers and control platforms that can be employed for the real-time implementation of MPC algorithms are presented. Finally, the MPC schemes in question are assessed, among others, in terms of design and computational complexity, along with their performance and applicability depending on the power electronic system at hand.

“…Since this paper obtains a high-precision and wide-range photovoltaic cell simulator by following the I-V curve of the photovoltaic cell with power electronics, it is necessary to give the illumination intensity and temperature parameters of the photovoltaic panel, and then the IV curve can be uniquely determined according to the idc1 and V dc of the load end, whereby the system can follow the output characteristics of the photovoltaic panel according to closed loop control. The I-V curves of photovoltaic panels at different light intensities and temperatures can be obtained from Equations (5)- (7).…”

“…et al [6] discussed the use of space vector modulation techniques to enhance the performance of a bidirectional three-SCR four-switch hybrid current source converter (HCSC). Gao, H. et al [7] presented a model predictive switching pattern control for a current-source converter (CSC), which achieves superb low-order harmonics elimination performance in steady state and improved transient responses. Due to the overlap time causing negative influence in the output current waveform, Geng, Y. et al [8] proposed overlap-time compensation method, which can effectively decrease the current harmonics introduced by the overlap time and improve the output current of the inverter.…”

Aiming at the function and technical requirements of high-power photovoltaic cell simulation, high-performance programmable logic power supply and dc motor simulation, a high frequency isolation hybrid topology and control strategy based on current-source/voltage-source converter was studied and proposed. Firstly, according to the performance requirements of photovoltaic cell analog power supply, the control strategy requirements of the high-precision wide-range hybrid topology were proposed. Secondly, the working principle of the new hybrid topology was analyzed. At the same time, the equivalent model of the new hybrid topology was simplified and established, and the overall control strategy of the hybrid topology based on current compensation and sliding mode variable structure was proposed. Finally, simulation and experimental research on the hybrid topology was carried out, and the experimental test of photovoltaic cell simulation was completed. The simulation and experimental results show that the hybrid topology and control strategy proposed in this paper has the characteristics of wide-range output regulation, fast dynamic response, high efficiency and high power factor, and can be used for high performance photovoltaic cell simulation, programmable logic power supply and DC motor simulation.

“…However, the large number of voltage vectors and redundant switching states in the multilevel inverter has made the multilevel SVM algorithm complex, so the SVM is widely adopted in two‐level and three‐level modulation algorithms. Several effective methods have been presented to optimize the multilevel SVM algorithm based on the two‐level SVM or the equivalent coordinate system . For different applications, some modulation algorithms have been proposed , which are mainly applied to structures based on the two‐ and three‐level NPC.…”

In the high-power five-level neutral point clamping/H-bridge (NPC/H) inverter, the traditional space vector modulation (SVM) algorithm at a low switching frequency has the disadvantages of a high-voltage jump at high modulation index and an inherent narrow pulse at low modulation index, which may cause serious damage to the power stage. In this paper, a novel SVM algorithm is proposed to suppress the high-voltage jump and narrow pulse for the five-level NPC/H inverter with a high-power integrated gate-commutated thyristor (IGCT). An equivalent three-level NPC model is applied to reduce the redundant switching state. To suppress the high-voltage jump at high modulation index, the switching state optimization method is proposed. Moreover, the zero sequence voltage injection is proposed to suppress the narrow pulse at low modulation index. Finally, the novel SVM algorithm is experimentally tested on an experimental prototype and an engineering prototype for 6.6 kV to 20 MW motor drive system. The simulation and experimental results verify the effectiveness of the proposed SVM algorithm.He Liu (Non-member) He received an M.S. degree in power electronics and power drives from the school of Information and Electrical Engineering, China University of Mining and Technology in 2012 and is presently working toward a Ph.D. inform the School of electronic information and electrical engineering, Shanghai Jiao Tong University.
