“…Roy et al [23] developed a cross-switched inverter based on switched-capacitor-converters, it utilises an optimum number of switches, however, its five-level version includes two capacitors, which would lead to more control complexity. Another distinct five-level topology is presented in [24]. However, it requires seven-switches, four-diodes, and two capacitors to generate the required five-level output.…”

Multilevel inverter configurations are a suitable candidate for medium and high power applications. This study presents a new one-capacitor-based five-level (2V dc , V dc , 0, −V dc , − 2V dc) boost multilevel inverter. The single-phase version of the proposed formation has one dc-source, eight switches and one capacitor. To provide boosting ability, the inverter is operating based on charge-pump theory, where the capacitor is charging in parallel and discharging in series connections to provide a higher output voltage. The proposed configuration requires simple control tasks, and for this purpose, level-shift pulse width modulation strategy, where the reference signal is compared with four carriers, is implemented to drive the switches and generates the required pulses pattern. The developed inverter has some distinct features like the usage of only one dc-source and one-capacitor, compact size, simple control requirements and boosting ability. The system is simulated with MATLAB/ Simulink and a hardware prototype is developed to verify the performance of the developed five-level configuration. The results show that the developed five-level multilevel inverter reaches the expected performance

“…The topology (Sajadian and Santos, 2014) requires the use of a transformer, which can be a disadvantage, but it only requires a single source and no capacitors for obtaining the five voltage levels. Topologies (Sajadian and Santos, 2014;He and Cheng, 2016;Vahedi et al, 2016;Gautam et al, 2017;Saeedian et al, 2018) require a single dc link, i.e., a split dc link is not necessary for the operation with five levels; therefore, for applications as renewables, this is an interesting aspect. Since fault tolerance and reliability issues are not the main focus of this review, only a few examples of the more recent topologies (Madhukar Rao and Sivakumar, 2015;Gautam et al, 2017;Hu et al, 2018) were considered.…”

A new structure of switched capacitor multilevel inverter (SCMLI) capable of voltage boosting and with self-balancing ability is introduced in this article. This advantage is the result of a step by step rise of capacitor voltages in each module, supplied by just one DC voltage source. The proposed topology generates a sinusoidal output waveform with a magnitude several times greater than the input one. Higher output staircase AC voltage is obtained by applying a nearest level control (NLC) modulation technique. The most significant features of this configuration can be mentioned as: fewer semiconductor devices, remarkably low total harmonic distortion (THD), desirable operating under high /low frequency, high efficiency, inherent bipolar voltage production, easy circuit expansion, ease of control and size reduction of the circuit thanks to utilizing neither bulky transformer nor inductor. Moreover, the proposed SCMLI is comprehensively surveyed through theoretical investigation and a comparison of its effectiveness to recent topologies. Eventually, the operating principle of a 25-level prototype of the suggested SCMLI is validated by simulation in the MATLAB SIMULINK environment and experimental results.
