Opis

This book presents the analysis of 3, 4 and 5- level diode clamped converter that is based on the space-vector pulse width modulation technique which is considered as the most efficient and digitally applied modulation scheme. This technique was compared with another controlled modulation method which is based on the multi-carriers/sinusoidal pulse-width modulation with an injected third order 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 subchapter 3.4. In line with the above analysis is a small scale laboratory designed-experimental work that was constructed to verify the simulation results obtained from the SIMPLORER simulations for the un-modulated three-level diode clamped converter.
