Hello friends, After such a long break, I want to share a Matlab/Simulink model which I made for simulating 9 level cascaded multilevel inverter as mentioned in the title of this post. To be precise, this post deals with Single Phase Multilevel Inverter.

Usually the objective of multilevel inverter designers is to get a purely sinusoidal wave out of a Constant or variable DC Voltage source or current source. The inverters using DC Voltage Source are called VSI i.e. Voltage Source Inverters while the inverters made using Current source are ca ....etc

The power electronics device which converts DC power to AC power at required output voltage
and frequency level is known as inverter. Inverters can be broadly classified into single level
inverter and multilevel inverter. Multilevel inverter as compared to single level inverters have
advantages like minimum harmonic distortion, reduced EMI/RFI generation and can operate on
several voltage levels. A multi-stage inverter is being utilized for multipurpose applications, such
as active power filters, static var compensators and machine drives ....etc

Diode Clamped Multilevel Inverter Fed Induction Motor


INTRODUCTION

Two level voltage source inverters produce an output voltage or a current with levels either 0 or Vdc

In high power and high voltage application these two level inverters, however, have some limitations in operating at high frequency mainly due to switching losses and constraints of device ratings.

Unique structure of ML-VSIs allow them to reach high voltages with low-harmonics without use of transformers ....etc

Abstract

Multilevel inverters generate stepped AC signals and thus overcome many of the limitations with the classical inverter circuit. Multilevel inverters use many number of switches and generate staircase type output through controlled switching of various switches. The sequence of switching and the duration of each step are very vital in minimizing the THD. The methods of generating gating signals are not unique. Many methods that are proposed in literatures make use of SPWM technique. Sinusoidal Pulse Width Modulation (SPWM) is a popul ....etc

Abstract:
Among the various power quality problems, the voltage sags, are attracting a large amount of attention of researchers from industry. DVR gives the solution to the above mentioned problem. The main function of DVR is to mitigate the voltage sag. It controls voltage applied to the load by injecting voltage of compensating amplitude, frequency and phase angle to the distribution line. The DVR is primarily responsible for restoring the quality of voltage delivered to the end user ....etc
