Multilevel voltage source inverter offer several advantages compared to their conventional counterparts. Cascaded H-bridge inverter provides Stepped AC voltage wave form with lesser harmonics at higher levels by combining different ranges of voltage DC sources and the filter components are reduced by increasing Step levels. By increasing the level of the inverter we can get several advantages: ...

The electrical characteristics of an isolated induction-generator-based system are improved through the association with a voltage-source pulsewidth modulation (PWM) inverter. The electronic converter allows the achievement of a better system behavior in many aspects: voltage regulation, frequency stabilization, and reactive power compensation. The system operation strategy consists of maintain...

In the viewpoint of reliability implication and cost effectiveness of three phase inverter, there should be less device count in inverter topology and fewer losses in the semiconductor switches. The earlier reported less device count topology by many research groups are facing the problem of Total Harmonic Distortion (THD). The imperfect design value of DC link capacitor is the main reason of H...

Multilevel inverters have become more popular over the years in high power electric applications without use of a transformer and with promise of less disturbance and reduced harmonic distortion. This work proposes three phase five level Diode Clamped Multilevel Inverter (DCMLI) to simulate various modulating techniques for induction motor load. These Pulse Width Modulation (PWM) techniques inc...
