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..

“…A 13‐level inverter shown in Figure 33 has voltage boosting ability six times the source voltage with inherent capacitor voltage balancing; the voltage balancing is achieved with simple logic‐based pulse‐width modulation technique; however, the maximum voltage stress across the switches reaches up to three times the source voltage 67 . Similarly, a recently developed 13‐level inverter topology shown in Figure 34 has a voltage gain of 6 and has been controlled with the hybrid combination of phase‐shift and level‐shift pulse‐width modulation technique 68 . A modular prototype represented in Figure 35 is of 13‐level, which is simple in design and has been extended to 13‐level inverter with voltage boosting ability six times the input source.…”

Summary Multilevel inverters are very popular in renewable energy applications. These inverters produce output voltages close to sinusoidal and have lower harmonics as compared to the conventional two‐level inverters as it also helps in reducing the size of the filter, thus makes the circuitry less complicated. In conventional multilevel inverter topologies, the number of devices increases with the increase of the number of output voltage levels, which in turn makes circuitry bulky and costly. Further, the boosting feature of the input voltage is also necessary for the application of multilevel inverters with renewable energy. Therefore, to reduce the count of devices, losses, and rating of devices, various switched‐capacitor multilevel inverter topologies are proposed. Switched‐capacitor multilevel inverter topologies (SCMLIs) can generate multiple voltage levels along with high voltage gain with a minimum number of devices. This paper gives a detailed overview of the recently introduced SCMLIs. The different SCMLIs have been categorized based on the number of levels and voltage gains. A detailed comparison has been introduced in this paper. Finally, few SCMLI topologies have been experimentally validated using the experimental results.

“…The modulation of the inverters is generally classified as either high-switching frequency modulation or low switching frequency modulation. Sine-PWM [24] and its variants like the ones presented in [18] and [11], space vector PWM [6] and hybrid modulation techniques [25] are some of the high- (a) 5-level PUC topology [8], (b) 9-level PEC topology [18], and (c) Presented topology.…”

This article presents an 11-level operation of the WE (Wee)-Type inverter. The topology employs a single DC-source, has a reduced number of components, and exhibits a boosting capability. A voltage balancing algorithm is proposed where the inverter's redundant states are employed to maintain the auxiliary DC-link voltage. It is shown that with the control algorithm, the link voltage is preserved at half the primary DC-link voltage, and the 11-level operation is possible for any load. The presented 11-level WEtype structure is also compared with recent 11-level structures and has a lowest cost factor. Two modulation strategies verify the 11-level operation of the inverter: first, a modified nearest level control (MNLC) with the usage of both zero states is developed; and, second, selective harmonic elimination (SHE) is employed, where the angles are generated using a differential evolution (DE) technique. The maximum efficiency of the inverter is 97.55 %. The performance of the inverter is validated in MATLAB/Simulink and on the hardware-in-the-loop platform.INDEX TERMS WE-Type Inverter, 11-level operation, boosted output voltage, modified nearest level control, differential evolution, selective harmonic elimination.
