“…Although the proposed new l ‐factor method includes simple arithmetic calculations [19], the number of operations and stages needed is greater than that in the previous algorithms. The principal limitation of this approach is that, in some cases, the computed switching times could be greater than the switching period or less than zero, which occurs unwanted approximations in the algorithm.…”

This study proposes a new simplified hybrid space vector modulation (HSVM) algorithm for multilevel diode clamped converter (DCC). The main idea consists in combining the advantages of both space vector modulation (SVM) algorithms synthesised in abc and αβ coordinates to establish a new hybrid, simplified and generalised SVM algorithm. The HSVM algorithm offers a simple method to compute the duration time, automatic generation of all redundant states of the adjacent switching vectors without triangles identification stage and switching sequence definition for any DCC level. Moreover, all the computational processes are performed in one unique sector thanks to the proposed new reference voltage vector defined in abc‐coordinates. The proposed algorithm does not require any coordinates transformation or lookup tables. Also, it can be implemented with minimum computational burden using a low resources digital platform. The proposed HSVM is verified through MATLAB simulation and validated experimentally using three‐level DCC laboratory prototype. For high‐level DDC, the HSVM is tested in real time using hardware‐in‐the loop testing technology. Different case studies are performed to demonstrate the high performance of the proposed HSVM and its ability in lowering the computational resources requirement.

“…Determine the switching time of each switch across all the regions. The SVPWM technique for three-level inverters is called "voltage-time equalization" principle [10]. For example, considering that the reference vector Vref is locating in sector I and in region 2, for this region, the nearest three voltage space vectors are V1, V7 and V2 are shown in Figure 4.…”

“…As compared with two-level inverters, multilevel inverters have multiple advantages, for example, low harmonics in output voltages and current, less dv/dt, lower power losses across switching devices, less common mode voltages, and higher quality output waveform [3][4][5][6][7]. Therefore a new family of multilevel inverters has emerged as the solution for different applications; such as, AC power supplies, large powerful engine drivers, transmission, distribution systems and medium voltage grid [8][9][10][11][12].…”

In this paper two very efficient pulse width modulation techniques were discussed named Sin pulse width modulation and space vector pulse width modulation. The basic structure of the three-level inverter neutral-point clamped is introduced and the basic idea about space vector pulse width modulation for three-level voltage source inverter has been discussed in detail. Nearest three vectors space vector pulse width modulation control algorithm is adopted as the control strategy for the three phase three level NPC inverter in order to compensate the neutral-point shifting. Mathematical formulation for calculating switching sequence has determined. Comparative analysis proving superiority of the space vector pulse width modulation technique over the conventional pulse width modulation, and the results of the simulations of inverter confirm the feasibility and advantage of the space vector pulse width modulation strategy over sin pulse width modulation in terms of good utilization of dc-bus voltage, low current ripple and reduced switching frequency. Space vector pulse width modulation provides advantages better fundamental output voltage and useful in improving harmonic performance and reducing total harmonic distortion.

“…The pulse width modulation (PWM), as a core technique of multi-level converters, has attracted widespread attention [2,3]. At present, the most commonly used multi-level PWM includes the carrier sinusoidal PWM (SPWM) [4][5][6][7] and the space vector PWM (SVPWM) [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The main role of the carrier SPWM lies in determining the on-off state of switches by comparing the amplitude of the triangular carrier with that of the sinusoidal modulation wave.…”

This Letter has proposed a synchronous control strategy of dual five-level converters based on the improved space vector pulse-width modulation (SVPWM). Firstly, the main topology of the neutral point clamped (NPC) five-level converter was introduced and its operational principle was analysed. Then, the space voltage vector diagram was offered. Considering the reduction of switching loss, the optimisation of the synthesis method of target voltage vectors and the addition of the neutralpoint potential balancing algorithm can lead to an improved SVPWM strategy for the five-level converter. The analysis of the switching rules proves that the improved SVPWM has an advantage over the traditional three-segment SVPWM due to its fewer times of switching. On the basis of the improved SVPWM, a synchronous control method of dual single-phase five-level converters is proposed to carry out a real-time control of the dual five-level converters through the combinational-encoding transmission of output pulses. Thus, the synchronous control method can, to a great extent, solve the problems caused by the traditional dual five-level independent control method, such as high hardware cost, the complexity of control, and poor synchronous performance. Simulations and experiments show that the proposed synchronous control method is feasible and effective.
