This paper presents the comparative study of three phase twenty five level diode clamped and cascaded H-bridge multilevel inverters. The comparison is made in respect of requirement of devices, quality of output voltage and reduction of total harmonic distortion at the multilevel inverter terminals. In this work multicarrier sinusoidal pulse modulation control methods of Phase disposition (PD-P...

The simple Selective Harmonic Elimination (SHE) for 3-Phase Voltage Source Inverter (VSI) is presented here. The proposed work is to examine the Selective Harmonic Elimination (SHE) and to eliminate harmonics produced by Pulse Width Modulation (PWM) inverter. The selective harmonic elimination method for three phase Voltage Source Inverter (VSI) is generally based on ideas of opposite harmonic ...

In today’s era power quality is the main issue mainly for welding load which includes the problems like total harmonic distortion, voltage sags, voltage swells, voltage distortions etc. In this paper we will discuss about the Total Harmonic Distortions for the welding load by using the simple modular dc-dc converter, modular bridge dc-dc converter and by using the ZSource Converter using Dynami...

The impact of electric car charging stations on power grid harmonics is growing as their existence continues to expand and creates harmonic distortion in the system. At same time, quality current voltage through process charge becomes inferior. Therefore, reduction output ripple factor (RF) mitigation input vital this situation. This paper presents design filter three kinds shunt passive filter...

In this paper control of Goertzel Algorithm based shunt active power filter with sliding mode controller is considered. Shunt active power filter involves harmonics mitigation due to three phase non linear loads under balanced and unbalanced load conditions. The sliding mode controller is used to regulate voltage of the capacitor used in inverter. The sliding mode controller improves the dynami...
