“…Output varies from ±+9nE for 'n' units. V. FUTURE TRENDS Although, many RSC-MLI topologies are reported in open-loop with RL load, a few RSC-MLI configurations are reported for specific applications such as PV [167][168][169], adjustable speed drives [170][171][172][173], power quality [174], FACTS [175], solid-state transformers [176], energy storage [177,178], electric vehicles [179], wireless power transfer [180] and power factor correction [181,182]. While, the RSC-MLI topologies are widely popular in academia from the past decade, they are yet to be penetrated in commercial applications.…”

An efficient and cost-effective power converter is a pre-requisite for the modern power applications. With the evolvement of matured medium power self-commutated switching devices, multilevel inverters (MLIs) are emerged as a promising solution for high-power medium-voltage applications. Though, MLIs are performing a promising role in industrial applications, their high device count, size, cost and control complexity have restricted their market penetration. To address the disadvantages of MLIs, researchers are continuously contributing to new generation topologies under the name of reduced switch count (RSC) MLIs. From the past decade, numerous RSC-MLIs topologies have been reported for various applications. Therefore, this paper presents a comprehensive review and classification of RSC-MLI topologies, in terms of their structure, features, limitations, suitability and selection for specific applications..

“…From the literature survey, the transformerless DC-DC converters are Conventional Boost Converter (CBC), 28 High Step-up Boost Converter (HSBC), 29 Modified Single Switch Boost Converter (MSSBC), 30 and Three-Level Bidirectional Single Switch Converter (TBSSC). 31 The CBC is used in most of the solar PV standalone power generation systems because of its attractive features are less magnetic inrush current, high flexibility, continuous power supply, and low power losses. 28 The disadvantage of CBC is less voltage conversion ratio that can be overcome by HSBC.…”

Under Partial Shading Conditions (PSCs), the solar PV nonlinear characteristics consist of multiple Maximum Power Points (MPPs). As a result, it is very difficult to extract the peak power of the solar PV. In this article, an Improved Grey Wolf Optimization‐based Fuzzy Logic Controller (IGWO‐FLC) is proposed to track the MPP of the solar PV. The advantages of the proposed hybrid soft computing Maximum Power Point Tracking (MPPT) controller are high accuracy, very less oscillations across MPP, and high tracking speed. Also, a new transformerless, high step‐up, Non‐isolated Boost Converter (NIBC) is introduced in this work to improve the voltage profile of the solar PV system at different atmospheric conditions. The introduced converter circuit makes use of the network LC3D3 to improve the voltage conversion ratio, reduced voltage stress on switches, and universal input voltage. In addition, the network LC3D3 acts as a filter to reduce the output power ripples of the converter. The steady‐state performance of the proposed converter is analyzed at Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) of operations. The MATLAB/Simulink window is used to validate the proposed PV fed NIBC system at uniform and different PSCs of the solar PV. Also, the NIBC performance is investigated by applying an M62252P8020 type programmable DC‐source.
