SPACE VECTOR PULSE WIDTH MODULATION FOR 3, 4 AND 5 LEVEL DIODE CLAMPED CONVERTER WITH EXPERIMENTAL VERIFICATION OF 3-LEVEL UN-MODULATED DIODE CLAMPED CONVERTER

📄 Project Abstract

This thesis presents the analysis of 3, 4 and 5- level diode clamped converter that is centered on the space-vector pulse width modulation technique which is considered as the most efficient and easily applied modulation technique in comparison with another controlled modulation technique which is based on the multi-carriers/sinusoidal pulse-width modulation with an injected third harmonic signal. It also focuses on the step by step development of MATLAB/SIMULINK modeling of the space vector pulse-width modulation and the multi-carriers/sinusoidal pulse-width modulation with an injected third harmonic based on the 3, 4 and 5-level inverter waveforms at 0.4, 0.6 and 0.8 modulation indices and their corresponding spectral results. The MATLAB simulation results obtained from the direct application of 3-level Voltage Source Inverter VSI on 10HP, 400 Volts, 50Hz induction machine drive are also presented in sub-chapter 3.4. In line with the above analysis is a small scale laboratory designe...
