“…The controlled switches (Sx1-Sx4) are employed as inner leg switches and Sx2 and Sx3 are employed as outer leg switches. When the position of the switches is change in operating mode like as inner (Sx1-Sx4) or outer (Sx2-Sx3), then short circuit will appear on the outer leg switches [13][14][15][16][17][18].…”

In recent years Multilevel Inverter (MLI) getting in popular due to its performance in field of medium and high-power applications. Many MLI’s like Diode-clamped, cascaded H-bridge, flying capacitor and hybrid cascaded H-bridge are introduced in 1970’s. But due to the draw backs like harmonic distortions researchers are concentrated on novel topologies. Recently nested configuration is gaining attention to researchers due to it is having an advantage of 3-phase design with a smaller number of components compared to traditional MLI topologies. Hence, this paper investigates the performance an advanced MLI named as Nested topology for 72V electric vehicle (EV) motor drive application for 1kW/1500 RPM system. It can generate near-sinusoidal voltages with only fundamental switching frequency, there is no electromagnetic interference (EMI) and also it gives easy operating EV and safer conditions. Furthermore, this paper inspects the analysis, benefits and control scheme for nested MLI for the use of EV motor drive applications. The simulations are carried out using Matlab/Simlink.

“…Therefore, the MLI is more suitable for medium/high voltage and high-power applications. Although there are many MLI topologies available [9][10][11], the most prevalent MLI topologies are neutral point clamped MLI (NPC-MLI) [4], [12], [13],…”

Cascaded H-bridge multilevel inverters (CHB-MLI) are employed in a variety of medium/high power applications. These inverters are known to inject unwanted harmonics into the grid, which negatively affects the grid and connected loads. CHB-MLI topology can reduce many of these harmonics by producing multiple output voltage levels and improves the fundamental component using a suitable modulation technique. However, the CHB-MLI topology configuration requires multiple isolated input sources which must be balanced either with the modulation technique or with an additional method. This paper analyzes multi-carrier pulse width modulation (MC-PWM) techniques for CHB-MLIs. In this study, two basic configurations of CHB-MLI symmetrical and asymmetrical are reviewed, followed by their mathematical analysis. Also, this paper analyses multicarrier based sinusoidal pulse width modulation (MC-SPWM) and multi-carrier based third-harmonic injected pulse width modulation (MC-THIPWM) techniques with phase-shifted (PS) and level-shifted (LS) carrier arrangements for the CHB-MLI. Moreover, a simulation study has been conducted using MATLAB Simulink to analyze the performance of MC-PWM techniques for the symmetrical and asymmetrical type CHB-MLIs. The 7-level and 9-level CHB-MLIs were evaluated for the stated MC-PWM techniques in terms of harmonics and fundamental components. In addition, discharging current of all input sources was checked to verify the ability of all MC-PWM techniques to balance all input sources.
