  Increasing the voltage of energy sources, such as photovoltaic (PV), fuel cells, and battery storage units, requires a voltage-boosting technique. This paper introduces an efficient switched-capacitor multilevel inverter (SC-MLI) capable of generating a boosted seven-level output voltage. The key advantages of this topology include the inherent self-balancing of capacitor voltages without the need for auxiliary balancing technique....

  - IEEE Access - Rok 2025

  Increasing the output voltage of sources such as photovoltaic (PV), fuel cells, and battery storage devices requires a boost action. The proposed switched capacitor multilevel inverter (SCMLI) topology incorporates nine power semiconductor switches, a dual DC voltage source, and a single capacitor, capable of generating a nine-level output voltage with dual voltage gain. Additional features of the proposed SCMLI topology include...

  - Rok 2024

  Switched capacitor multilevel inverters (SCMLIs) are highly popular for their ability to produce highquality output voltage with less total harmonic distortion (THD). The main feature of this topology is that it require a low number of power switches (seven switches) compared to the existing 5-level inverter topologies. Apart from the dual voltage gain, self-voltage balancing of capacitor voltage without any auxiliary control technique...

  The provision of isolated- and non-isolated DC output voltages by Power electronics power-conditioning devices in the recent ‘green-energy-revolution’ era is on course. In this paper, a structure for multi-input multi-output(MIMO) DC–DC buck converter is proposed to generate output voltages of varying levels with fewer component-count. The DC output voltage of each of the constituting buck converters can be used independently or...

  - IEEE Access - Rok 2024

  Galvanic isolation is a vital part of a grid-connected solar PV system. With the growth of multilevel inverters for grid-connected applications, the multilevel inverters having isolation are not sufficiently discussed in the literature. In this paper, a 15-level isolated multilevel inverter topology requiring only thirteen switches is proposed. The envisaged configuration includes two cells, designated as upper and lower cells....
