This paper proposes asymmetric cascaded H-bridge multilevel inverter with reduced number of switches suitable for industrial applications and renewable energy too. Cascade Multilevel Inverters are very popular and have many applications in electric utility and for industrial drives. When these inverters are used for industrial drive directly, the THD contents in output voltage of inverters are ...

In this paper presents a symmetrical five level cascaded inverter topology for Induction motor drive. It can continuously works at lower power stage. For this symmetrical circuit, when the number of level is increased, the voltage and power will also get increased. For reducing harmonics the Sinusoidal PWM method is used. The multilevel inverter gives the output to drive the three phase Inducti...

In this paper, an H-bridge inverter topology with reduced switch count technique is introduced. This technique reduces the number of controlled switches used in conventional multilevel inverter. To establish a single phase system, the proposed multilevel inverter requires one H-bridge and a multi conversion cell. A multi conversion cell consists of three equal voltage sources with three control...

This paper presents a new control technique to regulate the capacitor voltage in cascaded multilevel inverters. Without requiring transformers, the scheme proposed here allows the use of a single dc power source with the remaining n − 1 dc sources being capacitors. This paper focuses mainly to achieve an effective capacitor voltage regulation with the Phase shift modulation and energy storage u...

Multilevel inverters have an attracted a great deal of attenuation in medium voltage and high power application. Due to their lower switching losses, EMI, high efficiency. Among the several multilevel inverters topology it is more attractive due to the simplicity of control. This paper proposes to CHMLI output voltage level is increase to reduced total harmonic Distortion. Hence the paper mainl...

— Recent advances in solid-state semiconductors have led to the development of medium voltage power converters which could obviate the need for the step-up transformers of renewable power generation systems. The modular multilevel cascaded converters have been deemed as strong contenders for the development of medium-voltage converters, but the converters require multiple isolated and balanced ...
