Abstract
The rapid development of high switching frequency power electronics devices in
the past decade leads towards wider application of Voltage Source Inverters (VSI) in AC
power generation. Therefore, this prompts the need for a modulation technique with less
Total Harmonic Distortion (THD), less switching losses, and wider linear modulation
range. Space vector Pulse Width Modulation (SVPWM) provides a better technique
compared to the more commonly used PWM or Sinusoidal PWM (SPWM) because of
their easier digital realization and better DC bus utilization.
The conventional means of implementing SVPWM needs a lot of processing time
and high implementing cost. The present thesis presents SVPWM technique based on a
reduced computation method which is much simpler and more executable than
conventional means without complex logical judgments. Also the present thesis presents
a full detailed system design and practical implementation of space vector modulation
technique for driving three phase two level voltage-source inverters.
The SVPWM scheme is modeled / simulated using MATLAB SIMULINK
software package, and experimentally implemented / verified on the low cost microchip
PIC microcontroller 18F4431 platform. The experimental results are presented for three
phase two-level inverter followed by three phase LC filter.
