Multi-level voltage source converter is integrated in various fields in renewable energy power generation technologies such as wind and solar sources for applications that need higher voltage and higher power. In wind power generation market, doubly fed induction generator (DFIG) based on wind power generation is now the leading technology as they are economically feasible, they do offer a variable speed and efficient substitute to the fossil fuel. This paper proposes a DFIG based on a back to back diode clamped multilevel converter systems (DCMLI) fired comparatively by sinusoidal pulse width modulation (SPWM) and third harmonic injection pulse width modulation (THIPWM) techniques. By using these technologies, the DFIG performance is compared for different wind speeds under normal operation condition. The proposed approach shows that the DCMLI systems generate a near sinusoidal voltage with lower values in total harmonic distortion (THD) thus, upgrading the power quality that is produced by DFIG. Lastly, the variation of frequency of induced rotor voltage and the active power flow due to the wind speed changes when the rotor speed changes from super synchronous to sub synchronous speeds is investigated.

“…Multilevel converter (MLC) has been attracting considerable interest since it was discovered in 1981 [1]. It has great advantages over traditional two‐level converter, especially in the medium/high power applications [2–4]. Diode clamped converter (DCC), flying capacitor converter and cascaded H‐bridge are the main MLCs topologies [2–4].…”

“…However, it has some concealed limitations such as, further complexity of the algorithm due to the use of the three‐dimensional SVD, difficulty to design overmodulation and the absence of symmetries in SVD that can help to simplify the algorithm. On other side, using αβ coordinates, the SVM algorithm is designed in 2D plan, and it is known not only by its good symmetry of switching states between sectors and triangles but also by its easy overmodulation implementation [4, 8, 12, 13–18]. However, it also suffers from some weaknesses such as utilisation of coordinates transformation and trigonometric functions, which increase computational burden.…”

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.
