Background:: In multilevel inverters (MLI) as the number of level increases, there is a proportionate increase in the count of the semiconductor devices that are employed. Methods:: An asymmetrical multilevel inverter topology using a bidirectional switch is presented which employs lesser number of power electronic devices to produce fifteen levels at the output voltage. Nearest Level modulation (NLM) technique is used to generate the switching pulses and reliability analysis is performed using Markov reliability methodology. The operating principle of the proposed MLI and its performance abilities is verified through MATLAB/Simulink and a prototype is developed to provide the experimental results. Results:: Total Harmonic Distortion (THD) is computed for proposed MLI for different types of loads in simulation environment as well as in the developed hardware prototype. The fifteen level is achieved by using only 9 switches and 3 DC sources in comparison to the 28 switches and 6 DC sources required by the traditional cascaded H-bridge inverter. Conclusion:: The simulation and hardware results confirm the suitability of the proposed fifteen level MLI as the total component count and the requirement of DC sources reduces considerably.

<p>This paper presents a novel topology of Single-phase multilevel inverter for low and high power applications. It consists of polarity (Level) generation circuit and H Bridge to generate both positive and negative polarities. The proposed topology can produce more output voltage levels by switching dc voltage sources in series and parallel. The proposed topology utilizes minimum number of power electronic devices which leads to the reduction of cost, size, and weight low and consumes low power which improves the efficiency. Switching pulses are generated using Phase disposition (PD) pulse width modulation technique. Finally the effectiveness of the proposed topology is verified using MATLAB/SIMULINK software tool. 7level asymmetrical multilevel inverter prototype hardware is prepared to support the proposed topology to verify the effectiveness and its validity.</p>

<span lang="EN-US">Generally, PV cell converts sunlight into electricity in the form of dc. Integration of PV system with the existing grid requires dc-ac conversion. This conversion is possible with the help of a dc-ac converter known as an inverter. Among all types of the inverter, multilevel inverters (MLIs) are playing a major role with all their major privileges like High power quality, low distortion, less blocking voltages for switching devices. Conventional multilevel inverter topologies such as diode clamped, flying capacitor and cascaded MLIs are having so many disadvantages. One of the common disadvantage among all the conventional MLIs is the requirement of more number of power electronic components as the level of the output voltage increase. To reduce the power electronic components this paper proposes a multilevel inverter topology in symmetrical and asymmetrical configuration. The proposed MLI uses 12 switches and 19 diodes which are very less compared to conventional MLI topologies for generates nine and thirteen level output voltages. Comparison between presented MLI topology and conventional MLI topologies is presented in this paper. Finally, the proposed MLI whose input is fed from the PV system is integrated into the grid. The proposed concept is validated by using the MATLAB/SIMULINK software and the appropriate results are presented in this paper.</span>

In this paper, a new basic 15-level inverter is proposed. By developing the proposed basic unit, a 71-level inverter and generally an [Formula: see text]-level inverter are proposed. Then, the proposed multilevel inverter is compared with several conventional multilevel inverters in design of minimum 15 levels and 71 levels at the output. By comparing these inverters, it is obtained that the proposed inverter is able to generate higher number of output levels by using lower number of DC voltage sources and power electronic devices that lead to decreased complexity, installation space and total cost of the inverter. Finally, the correct performance of the proposed inverter is reconfirmed through the simulation and experimental results of a 15-level inverter.

Reduction in the overall power devices such as power semi-conductor switches, gate drivers with the associated circuits and DC voltage sources reduces the size, cost, complexity in addition with enhancing the overall performance of the inverter. This paper presents a new and generalized multilevel inverter topology with reduced number of power components. To identify the significance of proposed inverter, the generalized formulae for all the parameters are calculated and a comprehensive comparison of different performance parameters are presented in tabular as well as in graphical form. Multicarrier pulse width modulation strategy is adopted for generating the switching pulses. Simulation of the proposed MLI topology for the 9-level and 17-level inverter have been performed in MATLAB/Simulink and the corresponding experimental results are incorporated for one unit and two units, respectively, experiments are carried out at RL load. Nevertheless, level per switch Ratio (L/S) is introduced and compared with some of the new discussed MLI topologies. Moreover, the switching and the conduction losses of the inverter are also calculated and incorporated in this paper.
