“…Multi-Level-Inverter(MLI) are best for medium and higher power application [8] and are more worthy for Renewable-Energy-Sources(RES), due to its reduced disturbances and operation at lower switching frequency [9]. It provide smoother output waveforms due to increased number of level and hence a considerable reduction in Total harmonic distortion(THD) [10,11]. There is an inverse relation between Total harmonic distortion and number-of-levelsNL, if the number-of-levels are increased such that it reaches to infinity, the total harmonic distortion will be zero [12].…”

Electricity demand is continuously increasing due to dependency of industrial, commercial and residential users on advance technology. To address this issue is the prime need of time. Modern trend is to harvest energy from renewable sources such as wind, PV etc, which is environmental friendly and economical comparatively. However, as Renewable-Energy-Sources (RES) are sprinkled in small scale by the nature, so usually it is difficult to get a scalable amount of energy. Furthermore, the power quality is much affected due to varying nature of these RES sources. To get maximum efficiency and reliable operation from RES, different inverter topologies are presented. This paper highlights four types of Multilevel-invertertopologies commonly used for smoother, reliable and efficient operation of renewable energy sources (RES) in medium and high power applications. These are NeutrallPoint-Clamped-(NPC) or also called Diode-Clamped MultiiLevel-Inverter(DCMLI), Flying-Capacitor(FCMLI), Cascaded-Inverterr(CMLI) and a Hybrid/ Mixed MultiiLevel-Inverter topology(HMLI/MMLI). Each topology when used with renewable energy sources has its own features with corresponding advantages and disadvantages. This review is based on controlling methodologies, Total-Harmonic-Distortion (THD), construction complexity and components need for the respective topology. Multi-level-inverter (MLI) has the advantage of extinguishing the need of passive filtering at the grid side, and hence efficiency of the grid and cost minimization can be achieved.

“…However, the authors present the multilevel topology simulation generating of 9‐ and 27‐levels, but only an experimental prototype to generate 9‐levels is implemented, which is acceptable but not enough, since the control strategy to generate 27‐levels through the proposed topology is not detailed. In Raveendhra et al, the control of cascaded H‐bridge in a photovoltaic system based on sinusoidal PWM techniques through an FPGA is reported. This is a potential application; however, the authors only report the system simulation.…”

SummaryIn this paper, a digital sinusoidal pulse width modulation (DSPWM) multilevel technique of 27-levels based on field programmable gate array (FPGA) is introduced, as an alternative to control of the direct current/alternating current multilevel power converters. The implementation of this technique with an FPGA XC3S500E model is achieved in the Xilinx Spartan-3E FPGA platforms. An experimental prototype is implemented by 3-cascaded H-bridges controlled by the DSPWM multilevel technique, generating high efficiency, low cost, and lower harmonic content. The efficiency of the DSPWM multilevel technique using R, RL, RC, and RLC loads connected to the power network is verified.
