<span lang="EN-US">The conventional two-level inverter becomes no longer has the ability to cope with high-power requirement, so this paper discusses two very common topologies of multilevel like modular multi-level converter (MMC) and cascaded H-bridge (CHB) for induction motor drive applications. This work attempts investigate comparison between MMC CHB. The is done in aspects configura...

A new multilevel inverter (MLI) topology is proposedusing a level doubling network (LDN). The LDN takes the form of a half-bridge inverter to almost double the number of output volt-age levels. The concept (of the proposed LDN) has the capability of self-balancing during positive and negative cycles without any closed-loop control/algorithm, and it does not consume or supply any power. The topo...

This paper presents the necessity of portable power supplies that can be carried and cater to all users' demands. Since energy storage pack are coming from DC supply, it needs an inverter convert voltage into AC voltage. Most low-priced inverters in market have a simple build inefficient, resulting high THD cause electrical appliance not work properly. project was focused on most suitable type ...

In this paper, a seven level modified cascaded multilevel inverter is proposed for industrial drive applications. Apart from selecting the conventional level inverters, Multi level inverters has been chosen for the industrial drive applications as it reduces the total harmonic distortion. The involvement of higher number of switches increases the complexity of the system, which leads to losses ...

A detailed model and analysis of a five-level cascaded H-bridge (CHB) multilevel inverter with different current control methods are presented. Simulation models the CHB hysteresis controller, PI controller using SPWM technique predictive have been built to demonstrate system performance regard load THD reference tracking. In controlling current, controllers problem ripple phase lag, respective...
