“…The MMC (modular multilevel converter) is being considered extensively and is an extension of CHB. These topologies were primarily designed to consider power conversion in medium to high voltage applications like HVDC transmission [1], [7], [8]. However, the functional advantages of multilevel output can be extended to lower voltage levels.…”

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 detailed review on the recently published multilevel inverter topologies to find the most suitable applications with reduced device count is published in [7][8][9][10][11][12]. In the case of lower solar PV voltages, a high gain DC-DC converter along with multilevel inverter can be used to boost the PV voltage for obtaining desired output voltage for grid integration [24][25][26].…”

A new triple voltage boosting switched-capacitor multilevel inverter (SCMLI) is presented in this paper. It can produce 13-level output voltage waveform by utilizing 12 switches, three diodes, three capacitors, and one DC source. The capacitor voltages are self-balanced as all the three capacitors present in the circuit are connected across the DC source to charge it to the desired voltage level for several instants in one fundamental cycle. A detailed comparative analysis is carried to show the advantages of the proposed topology in terms of the number of switches, number of capacitors, number of sources, total standing voltage (TSV), and boosting of the converter with the recently published 13-level topologies. The nearest level control (NLC)-based algorithm is used for generating switching signals for the IGBTs present in the circuit. The TSV of the proposed converter is 22. Experimental results are obtained for different loading conditions by using a laboratory hardware prototype to validate the simulation results. The efficiency of the proposed inverter is 97.2% for a 200 watt load.
