“…Multilevel Inverters are the pathfinders of modern day Electrical and Electronics. Inspite of the fact that these inverters are utilized for medium voltage and high power applications, this proposed topology can likewise be connected for high power and high voltage applications [14,15] Conventional multilevel inverters incorporate controlled semiconductor switches for creating a high recurrence waveform of both positive and negative polarities [5]. In this technique there is no compelling reason for taking into consideration all the switches to create levels at both positive and negative polarity.…”

“…One prominent drawback of multilevel power transformation is the necessity of certain number of switches [4]. This ought to be noticed that minimal voltage appraised switches can be utilized as a part of the multilevel inverter [5,6]. Therefore, the active semiconductor cost isn't excessively expanded when contrasted with two level inverters.…”

<span lang="EN-US">Multilevel Inverters are generally utilized for medium voltage and high power applications. Invented in 1975, MLIs have brought huge change in the field of Electrical and Electronics. It contains distinctive topologies. This paper proposes a photovoltaic aided multilevel inverter with Reverse Voltage topology with diminished number of switches. In comparison to other existing topologies this topology utilizes minimum number of switches and less number of carrier signals which in turns diminishes the complexity of the system as well as cost. The proposed framework contains five MOSFETs, five diodes to create eleven levels. In this topology the SPWM strategy has been utilized. This topology utilizes one sine wave and five triangular waves, which is half in comparison to the existing topologies. As sustainable power sources can be utilized for multilevel inverter, photovoltaic cell has been utilized. The MATLAB recreation for both solar powered module and Multilevel inverter has been appeared alongside the equipment approach.</span>

“…There are generally three types of multilevel inverters: neutral point clamped (NPC) [9][10][11][12], flying capacitor (FC) [13][14][15][16], and cascaded H-bridge (CHB) [17][18][19][20]. NPC inverters have their inherent disadvantage, that is, the voltage distribution of capacitors connected in series on the power supply is uneven.…”

Due to the advantages of low harmonic, low pollution to the power grid, and easy filtering, multilevel inverters have attracted more attention in recent years. In this paper, a five-level inverter based on the differential structure is proposed. It doesn't need an additional bridge arm to change the polarity of the output voltage, but synthesize the structure of generating multiple voltages and changing the polarity of the output voltage. In addition, the special symmetrical structure of the inverter solves the problem of unbalanced capacitor voltage. The proposed five-level inverter is simulated by MATLAB/Simulink and the prototype is made to experiment.

A new modular multilevel DC-DC converter with high power density and simplified localized voltage balancing control is proposed. In the proposed configuration, converter building blocks with the same power handling capability are connected in parallel in each row. Converter building block consists of an H-bridge and mutually coupled inductors whose total current is nearly ripple free. These features are shown to reduce the voltage ripple of DC-link capacitors significantly, leading to a smaller capacitance and size. An optimized control algorithm with voltage feedback PI loop is proposed resulting in the elimination of current sensors. This, reduces overall system complexity and increases cost-effectiveness. Significant ripple reduction of the inductor current and capacitor voltages is observed based on the simulation and prototype of multi-level systems. With a fully modular power stage module and localized control module, a system of arbitrary number of level can be built by stacking modules thereby contributing to enhanced system redundancy.
