“…A new switched source MLI is proposed which operates under both symmetric Electronics 2021, 10, 368 2 of 23 and asymmetric mode. The proposed inverter is designed with six power switches and two voltage sources [9]. A new 81-level MLI is presented using two stage ladder circuits and the values of the dc sources are fixed by two different algorithms.…”

Multilevel inverter had been paid a lot of attention from the academia and research community in recent times due to its role in high and medium power applications. In this paper, a detailed survey is made on the recently designed multilevel inverter to find the suitability of the inverters for particular applications. Research is performed on various types of multilevel inverters such as: Symmetric, asymmetric, hybrid and modularized multilevel inverter in order to identify the issues in generating more levels at the output. A summary of various issues in multilevel inverter with reduced switch count is provided, so that a novel topology of multilevel inverter can be designed in future. Further, an 81-level switched ladder multilevel inverter using unidirectional and bidirectional switches is designed. Simulation work is carried out using Matlab/Simulink in order to validate the performance of the inverter with change in resistive load and impedance load. The output of the 81-level inverter is fed to a 110 V, 186.5 W single phase induction motor in order to study the characteristics, further speed control of motor is performed by varying the input voltage of the motor and the results are presented.

“…Thus, the requirement of filters reduces due to the inverter. Additionally, MLI provides extra advantages like enhanced efficiency, reduced the stress of dv/dt, lesser electromagnetic interference [12][13][14][15][16]. Among all the topologies for high power applications, the multilevel inverter is preferred [17].…”

The paper introduces the cascaded H-Bridge multi-level inverter with single-phase arrangement connected series with full-bridge inverter and CHBMLI configuration integrated with Double level circuit is proposed to reduce the harmonic distortion to get high power quality. In the proposed configuration, a half-bridge inverter has been implemented to increase the output voltage waveform nearly twice as compared with the conventional Cascaded H-Bridge MLI. For high Power quality, the output voltage waveform with the reference of sinusoidal, the phase opposition disposition carrier arrangement has been utilized in PWM for producing gate pulse of switches. The high waveform of output voltage achieved with the less no of switches, less % THD distortion, less conduction and switching losses. The purposed symmetrical model of CHBMLI is successfully verified using MATLAB based on simulation with DLC configuration.

In this paper, a ‘k’-state inverter producing a higher number of voltage levels was designed, and we studied the inverter’s working. Further, a tri-state inverter was derived from the ‘k’-state inverter, which could build a maximum number of output voltage levels with the requirement of fewer components, thereby reducing the cost and size. A single Tri-state architecture generates three direct current (D.C.) voltage levels; therefore, cascading five tri-state architectures can generate 242 levels of DC voltages. Further, the inversion is done via the H bridge, which leads to 485 levels of the output voltage. Algorithms to design the amplitude of voltage sources and the generation of pulses are discussed in this paper. The proposed tri-state inverter takes a significant role in advancing renewable energy systems in utilizing inverter technology. A simulation study validated the operation of the proposed inverter. Moreover, an experimental setup was built for a single-phase 485-level inverter, and the structure’s performance was verified through the experimental results.
