“…Multiple structures for the MLI have been presented to reduce the switch count. The structure realized in [13] is a 51-level symmetric structure consisting of 9 level structures in cascade with an H-bridge circuit. This structure has 25 independent sources, each having a magnitude of 1 volt, along with 46 power switches.…”

Design for asymmetrical Multi-Level Inverter without H-bridge and with minimal number of switch is presented in this paper. The proposed circuit is capable of generating 21 levels with only 10 switches and 3 unequal D.C. voltage sources. Operation of the proposed circuit is discussed in detail in this paper and there by framing the switching sequence for the proposed circuit. Simulation of the presented inverter is done for loads like resistive, reactive and induction motor. From the simulation results, inverter performance is analyzed in terms of THD.

“…Using Equations ( 2) and ( 3), 19 controlled switches and 10 DC sources were required to construct 485 voltage levels. DC source values were obtained from Equations ( 7) and (8). VT 11 , VT 21 , VT 31 , VT 41, and VT 51 are taken as 1 V, 3 V, 9 V, 27 V, and 81 V. The voltage values of VT 12 , VT 22 , VT 32 , VT 42, and VT 52 are considered as zero.…”

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.

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.
