Switched-Capacitor multilevel inverters (SCMLI) are being explored for renewable power applications like solar-PV integration because of their benefits of low component count and low-cost factors. This work presents and explores a new multilevel inverter with a hexad voltage-boosting capability. It employs a single source and produces a 13-level waveform by utilizing only fourteen switches, two diodes, and four capacitors. The voltage across the capacitors is maintained at the desired magnitudes during the switching of the inverter by connecting the DC source and capacitors in parallel at several time locations in one operating cycle. The topology proposed in this work is compared with the recent 13-level topologies in terms of switches, diodes, capacitors, and cost factors (CF). A level-shifted PWM-based algorithm generates the circuit switches' PWM pulses. The CF of the proposed SCMLI is found to be 2.461, which is the lowest among the compared hexad-boosted MLIs. Experimental validation is performed on a hardware prototype to validate various operational conditions of load change, modulation index change, and reference frequency change.INDEX TERMS 13-level operation, boosted output voltage, level-shifted pulse width modulation.

A robust iteration-dependent least mean square (RIDLMS) algorithm-based fundamental extractor is developed to estimate the fundamental components of the load current for a four-wire DSTATCOM with a nonlinear load. The averaging parameter for calculating the variable step size is iteration dependent and uses variable tuning parameters. Rather than using the current value, the previous learning rate was used in this method to achieve a more adaptive solution. This additional control factor aids in determining the exact learning rate, resulting in reliable and convergent outcomes. Its faster convergence rate and the avoidance of local minima make it advantageous. The estimation of the PI controller gains is achieved through a self-adaptive multi-population algorithm. The adaptive change in the group number will increase exploration and exploitation. The self-adaptive nature of the algorithm was used to determine the subpopulation number needed according to the fitness value. The main advantage of this self-adaptive nature is the multi-population spread throughout the search space for a better optimal solution. The estimated gains of the PI controllers are used for the DC bus and AC terminal voltage error minimization. The RIDLMS-based control with PI gains obtained using the proposed optimization algorithm showed better power quality performance. The considered RIDLMS-supported control was demonstrated experimentally using d-SPACE-1104.

“…The multilevel inverters (MLIs) with these features are widely accepted for grid-connected photovoltaic applications [1,2]. Variable frequency drives (VFDs), uninterrupted power supply (UPS), and several industrial drives [3] are some of the other uses of MLIs. Compared to previously available two-level inverters, the virtues of MLI arose from the increase in output voltage waveform performance.…”

A Generalized Switched-Capacitor Multilevel Inverter Topology with Voltage Boosting Ability and Reduced Inrush Current

This article presents a novel quadruple boost inverter (QBI) with an integrated boost stage that comprises an inductor, a capacitor, a switch, and an input source. The inductor on the input side limits the inrush current and also the capacitor charging current ripples. The QBI topology comprises a dc source, an input inductor, nine switches, three diodes, and capacitors. This produces a nine-level waveform, which reduces the need for additional filters such as inductors and capacitors. The proposed QBI is elementary, compact, and needs fewer components than existing nine levels inverter. Compared to the typical triangular carrier-based sinusoidal pulse width modulation, the newly developed parabolic level-shifted carrier has a much greater RMS value. Another advantage of the proposed topology is extension for generating higher voltage levels without increment in the blocking voltage across the switches. This makes the topology ideal for medium voltage high power applications. The output voltage has been determined in terms of selection, sizing, and expression. The proposed QBI is compared to existing similar nine-level inverters in order to assess its efficacy. The experiment is performed on a laboratory prototype to state the practical feasibility of QBI topology for the inductive load, variation in input, load, and modulation index.
