“…The MLIs generate the required high voltage without the use of transformers with low harmonics. Due to these remarkable features, MLIs are widely used in photovoltaic systems [10,18,19], wind energy conversion systems [8,25], fuel cells [26], traction [27][28][29], induction motors [30,31], active filters [32,33], wireless power transforms [34], HVDC [35,36], electric vehicles [37], and flexible AC transmission systems [38][39][40]. The MLI input is DC, which is obtained from wind conversion systems, fuel cells, photovoltaic panels, or energy storage devices.…”

This article presents a comprehensive review of reduced device count multilevel inverter (RDC MLI) topologies for PV systems. Multilevel inverters are widely used in medium-voltage and high-power applications such as wireless power transform applications, flexible AC transmission (FACT), active filters, AC motor drives, high-voltage DC transmission (HVDC), and renewable energy sources due to their high modularity and high-power quality output. Multilevel inverters have the ability to diminish the harmonics content in the output voltage by applying various modulation techniques. The literature in this field showed that the high-power quality and high modularity of the output demand an undeniable need for multilevel inverter topology. Research in this field has identified various multilevel inverter topologies, each possessing their own merits and demerits. The ubiquitous availability of multilevel inverter topologies illustrates the complexity of their accurate selection. To avoid such complexity, this review shows the state of the art of various reduced device count (RDC) multilevel inverter (MLI) topologies. Details of the various RDC MLIs, along with their comparisons, are provided in this paper. This review will be an important reference tool for future work on RDC MLI for photovoltaic (PV) systems.

“…The comparison shows that a nine level inverter can be realized with ten IGBT transistors for each phase. Unlike conventional systems such as NPC and cascade type inverters [29] [30] which require sixteen IGBT transistors, the proposed nine-level topology having less crowded and less expensive structure while maintaining the system performances.…”

In the scope of this work, a new structure of the nine level inverter is proposed using a reduced number of power switches. This inverter is used as a shunt active power filter to compensate harmonic currents and the reactive power. The modeling and simulation of the proposed model were carried out in Matlab/Simulink environment. The simulation results show that the filtering performances were achieved despite the reduction of the switches number. It was found that the current waveform becomes purely sinusoidal with a reduction in the harmonic distortion rate (THD) to 2.68%. This implies good compensation of both harmonics and reactive power with a power factor closer to unity. Reducing the switches number allows reducing the switching losses and lowering the duration of the applied voltage supported by the semiconductors. The proposed topology also allows to get simple structure of the inverter with a reduced cost.

“…As conventional low power and medium power SAPF is not fit to resolve present day power quality problems regarding effective compensation [4] and appropriate switching. Hence, engineers looked into MLI based architecture [5] instead of concentrating on control and placement issues, which sorted out compensation related issues. The present paper focus on the further enhancement capabilities of such developed cascaded MLI based SAPF (MLISAPF).…”

The usage of the word Power quality in recent times acquired intensified interest due to the complex industrial processes. The usage of intelligent tools to improve power quality is increasing day by day, as assumption of present day power system as a linear model is unsatisfactory. This paper deals with analysis of Differential Evolution (DE), Hybrid Differential Evolution (HDE) and Variable Scaling Hybrid Differential Evolution for harmonic reduction in the source current with optimal tuning of PI controller gain values. Shunt Active power Filter is one of the better solution to suppress the source current harmonics which are induced into power system because of nonlinear loads. Current controller called HBCC is considered for gating operation of switches in Voltage Source Inverter. The Intelligent tuned PQ theory is used for reference current generation. The then obtained compensating currents are injected at point of common coupling for current disturbance mitigation. Simulations of MATLAB/SIMULINK environment of the present work shows the efficacy.
