For medium voltage and high-power application generally, multilevel inverter is used as an energy conversion device. Advantages of multilevel inverter are lower switching losses, total harmonic distortion, less voltage stress on switches than conventional inverter.

This paper proposes Level shifted Pulse Width Modulation (PWM) methods for single phase transformerless Multi Level Inverter (MLI). Many of the existing topologies have high variations in Common Mode Voltage (CMV) and high leakage current. The proposed topology with level shifted PWM technique for five level single phase MLI, reduces the variations in CMV, minimizes the leakage current according to VDE0126-1-1 standard and the reduced number of switches makes the losses less than the conventional topologies.

Comparison of Multiple Carrier Disposition PWM Techniques Applied for Multi-Level Shunt Active FilterThis work presents the simulation of a shunt active filter using seven-level cascaded inverter. The ultimate objective is to bring out the influence of multiple carrier level shifted PWM techniques on the performance of a shunt active filter. Classical disposition PWM techniques such as PD, POD and APOD have been used to generate the gating signals for the inverter active switches.

Abstract:
In recent years, research in the area of multiphase drives has increased significantly. Having higher number of machine phases allows the current to be shared between the phases, thus reducing the current rating of power semiconductors used in the power converter. Additionally, if a multilevel inverter is used to drive the machine, the output voltage waveforms are going to be approximated closer toward sinusoidal waveforms, thus resulting in lower total harmonic distortion. Therefore, the combination of multiphase and multilevel technologies gives considerable benefits compared to conventional

Since the deployment of IP multicast remains restricted due to many practical and political issues, researchers have shifted focus to exploiting application-layer multicast for multicast data delivery. Recently there has been considerable interest in applying DHT routing algorithms to application-level multicast. However, early DHT-based multicast protocols are insufficient in addressing a number of technical issues such as heterogeneous capacity of nodes or node churn.
