FINAL YEAR PROJECT
THD ANALYSIS IN DIODE CLAMPED MULTILEVEL INVERTERS USING SELECTIVE
HARMONIC ELIMINATION PULSE WIDTH MODULATION
Project Objective was to analyze different levels of diode clamped multilevel inverters
for Total Harmonic Distortion.
Main Conclusion of this work was “decreasing THD trend with increasing number of
inverter levels”.
SIMPOWER SYSTEMS Toolbox in MATLAB was used as simulation software tool.
DIODE CLAMPED MULTILEVEL INVERTERS
Multilevel Inverters are different than ordinary inverters as regards the output voltage and
current waveforms. In case of multilevel inverters output waveform resembles a staircase
sinusoidal shape which is closed to a sinusoid as compared to ordinary inverters output. Due to
comparatively more sinusoidal like, it contains less content of total harmonic distortion. As the
inverter’s size is enlarged by adding more switches and diodes the harmonics are decreased.
Among three major types namely capacitor clamped multilevel inverter, Cascaded Multilevel
Inverters and Diode clamped Multilevel Inverter, the last one is selected for analysis because of
its simplicity of structure and modulation technique.
4. Total Harmonic Distortion
Total harmonic distortion is a measure of harmonic content in a signal. Harmonics in any
signal are unwanted signals which create power losses and thus decrease the efficiency of a
system. In addition Harmonics heat up a device and cables thus lowering the life span of devices.
SHE PWM and Angles Calculation
Each level/step of the staircase output waveform must be set on a specific interval in time
domain to eliminate a specific harmonic. SHE PWM includes a nonlinear set of transcendental
equations which can be optimized for certain number of harmonics that are to be eliminated from
output voltage/current. SHE PWM further provides the facility to mention the percentage of
fundamental harmonic and thus sustain it to that level. For angle calculations DOgLeg
Optimization technique is utilized with the help of MATLAB software. The structure of Diode
clamped Multilevel Inverter is then simulated in MATLAB SIMULINK in which the angles
from SHE PWM are used.
Fourier Analysis of Output Voltage
MATLAB provides further facility to perform Fourier analysis of any wave shape. The
resultant waveform from DCMLI output is then analysed for harmonics (Fourier Analysis).
Conclusions of Final Year Project
Diode clamped multilevel inverters five level, nine level and twelve level were simulated
in SIMULINK and analysed . It was observed that total harmonic distortion was
decreased as the number of levels were increased and thus a high efficiency of inverter
achieved. Diode Clamped Multilevel inverter proved best option as a back up supply in
high power industries.
