“…For powers of medium and higher ranges, the conventional two-level inverters are now substituted by such elementary MLIs as the flying capacitor (FC) inverters, neutral point clamped (NPC) inverters, modular multilevel converters (MMC), and cascaded Hbridge (CHB) inverters. Nevertheless, in order to attain a high number of output voltage levels, these conventional MLIs require more semiconductors (switches and diodes), capacitors, and DC sources [5][6][7]. To overcome *Corresponding Author Institutional Email: ja_siah@yahoo.com (J. Siahbalaee) these issues, researchers have proposed several switchedsource (SSMLI) and switched capacitor multilevel inverters (SCMLI) which need a lower quantity of devices to provide more voltage levels [8][9][10][11][12][13][14].…”

In this paper, a novel voltage-boosting switched-capacitor multilevel inverter (SCMLI) capable of producing 19 voltage levels using a combination of only 10 switches, 4 diodes, 2 capacitors, and 2 DC sources has been proposed. The main features of the proposed topology are 1) utilization of a very low number of devices, 2) very low Total Standing Voltage (TSV) equal to 6.55 and 3) self-balance property of the capacitors' voltages. In order to provide the IGBTs of the circuit with the desired switching signals, the Nearest Level Control (NLC) method has been adopted. To clarify the benefits of the designed topology as to the total quantity of switches, DC sources, capacitors as well as the total standing voltage (TSV), and converter boosting, a thorough comparison has been carried out versus the recently published 19-level topologies. Also, for the purpose of performance evaluation and validation, the suggested topology has been tested against various loads through an experimental setup in the laboratory using TMS320F28379D DSP as the processor. The comparative, simulation, and experimental results all imply the superiority of the proposed topology against its predecessor counterparts.

“…They have been rapidly used in photovoltaic systems [1][2][3][4][5][6][7][8]. The MLI are classified to three main groups: neutral-point clamped (NPC) [9,10], flying capacitor (FC) [11,12] and cascaded H-bridge (CHB) topologies [13,14]. In NPC and FC structures, the clamped diodes and capacitors are responsible for transmitting the input voltage to constitute the N-level voltage at the output, respectively.…”

A New Multilevel Inverter Based on Harvest of Unused Energies for Photovoltaic Applications

In multilevel inverters, unused energies are created due to the asynchronous use of the input DC sources. when the input DC sources are replaced by renewable systems such as photovoltaic arrays, some of the input energies remain unused. This paper presents a new multilevel inverter topology that can harvest the unused energies and return them to another output which leads to the harvest of the maximum input energy. The harvest of maximum energy (HME) based multilevel inverter structure consists of two terminals. One is connected to AC-load and another is joined to DC-load or rechargeable batteries. Another merit of the proposed multilevel inverter is that the number of its switches is comparable to other structures where unused energies cannot be harvested. Selective harmonic elimination (SHE) has been used as the switching strategy in the proposed multilevel structure. To verify the performance of the HME-based multilevel inverter topology, the experimental results for a type seven-level inverter were performed by the TMS320F28379D DSP.
