Single-source binary hybrid multilevel inverters with cascaded transformers have a bulky transformer connected to their main H-bridge cells in each phase. This bulky transformer has been eliminated in this work without any effect on operation and modulation strategies. The proposed topology has significant advantages from view point of dimensions and number of transformers, design of transforme...

Multilevel voltage source inverters have several advantages compare to traditional voltage source inverter. These inverters reduce cost, get better voltage waveform and decrease Total Harmonic Distortion (THD) by increasing the levels of output voltage. In this paper Genetic Algorithm (GA) and Particle Swarm Optimization (PSO) methods are used to find the switching angles for achieving to the m...

Several works have been reported in the literature on multilevel inverters topologies, control techniques and applications. However, there are few works that actually discuss or evaluate the performance of induction motor drives associated to three-phase multilevel inverter. This paper presents then a comparison study for a cascaded H-bridge multilevel DTC induction motor drive. In this case, s...

Power electronic converters, especially DC/AC Sinusoidal Pulse Width Modulation inverters have been extending their range of use in industry because of their numerous advantages. They typically synthesize the stair –case voltage waveform (from several dc sources) which has reduced harmonic content. This paper aims to extend the knowledge about the performance of Five level Cascaded H-Bridge MLI...
