An optimized multilevel inverter is implemented for 3 phase induction motor drive. The Main Feature Of this Circuit is to boost of the Battery Voltage as twice as possible along with multilevel staircase output voltage which approaches nearly sinusoidal wave. By using appropriate switching strategy of two capacitors the desired waveform can be achieved, hence significantly reducing the number o...

Power-electronic inverters are becoming popular for various industrial drives applications. In recent years also high-power and medium-voltage drive applications have been installed. However, the existing solutions suffer from some important drawbacks. Hybrid asymmetric multi-level inverters promise significant improvements for medium-voltage applications. This dissertation investigates such a ...

In this paper, analysis of cascaded H-bridge multilevel inverter in DTC-SVM (Direct Torque Control-Space Vector Modulation) based induction motor drive for FCEV (Fuel Cell Electric Vehicle) is presented. Cascaded H-bridge multilevel inverter uses multiple series units of H-bridge power cells to achieve medium-voltage operation and low harmonic distortion. In FCEV, a fuel cell stack is used as t...

Abstract This paper proposed a new voltage-boosting 13-level switched-capacitor (SC) cost-effective inverter. The topology comprises fourteen transistors, three capacitors and single DC source to produce staircase waveform. capacitor voltage balancing problem is inherently solved by the series/parallel technique.
