Significant interest has been shown in switched capacitor (SC)-based multi-level inverters (MLIs), which decrease the need for a DC supply and enhance power quality. The common issues with SC-MLIs include an uneven distribution of conducting paths, increased voltage drop across capacitors, the sum of all inverter DC link voltages across the highest voltage rated switches, and a higher total standing voltage (TSV). The purpose of this paper is to create a SC-MLI with less components in order to maintain a constant voltage across the capacitors, to obtain higher voltage gain with fewer parts, fewer conducting routes, lower TSV, and to create a more affordable and effective inverter. The structure of the MLI is created by a cascade interconnection between the number of SC cells. A single input multiple output (SIMO) converter boosts the DC-link voltage over the stable DC voltage of the solar panels using a modified perturb and observe (P&O) method. Additionally, fewer switches in the conduction path and 50 % of the switches operating at normal frequency guarantee a decrease in an overall loss of power in the proposed network. The benefits of the recommended MLI are made clear by comparing them with 17-level MLIs in terms of the number of elements, stress, gain, and cost factor. Detailed experimental results are shown under various transient conditions to show that the 17-level prototype is operationally viable. The total harmonic distortion (THD) is found to be identical and is less than 5 %, which meets IEEE standards.

“…A CHBMLI operated in trinary (1:3) voltage ratio for grid-connected loads is developed using a single input multi-output single-ended primary inductor (SEPIC) converter with 2-stage H-bridge inverters. The inverter system is potentially appropriate for grid-connected applications 4 . A combination of T-type as well as H-bridge inverters for producing nine-level output voltage has been suggested 5 .…”

The concept of an isolated DC source cascaded multilevel inverter finds good solutions for generating quality output voltage for low-medium power applications. It shapes the output voltage from three levels into a number of steps closer to a sinusoidal shape using small DC sources or batteries. Several advantages have been sighted like lower voltage stress and bearing noise, and lesser THD. However, a common issue in the MLIs is the total components required which increase with the rise in voltage levels. This paper proposes a three-phase MLI design having several isolated quad voltage source modules including an H-Bridge inverter. The design suggested claims reduced switching components for current conduction paths showing improved output quality. The operational features of the suggested MLI have been analyzed using Matlab/Simulink software, furthermore, an experimental module is constructed for demonstrating the effectiveness of the simulated results.

In this paper, an easily implementable method based on look-up tables is presented for balancing the neutral-point (NP) voltage in a five-level "Active NPC" topology for space vector modulation (SVM). In the proposed method, by utilizing the direction of output phase currents, operating region is divided into six zones. In each zone, there are two look-up tables; one for increasing the NP voltage and the other for decreasing the NP voltage. Since some look-up tables in different zones are identical, six individual look-up tables are obtained for controlling the NP voltage. In the proposed method, just few comparative operators and six look-up tables are utilized; therefore this method has proper implementation capability. Also, the proposed method is experimentally implemented on an active NPC converter which drives an induction motor via rotor field oriented control (RFOC) method. Experimental results verify performance, good dynamic response and effectiveness in balancing the NP voltage in low and high modulation index.
