Abstract

The  SVPWM technique has  become  more  popular today than  ever before due to the  availability of fast digital  systems  for implementing this  switching  scheme. This is the preferred switching scheme for three phase inverters when compared to traditional SPWM. This paper  describes  a modular implementation and  analysis  of three  popular  switching  methods employed  in voltage  source  inverters:  Space Vector Pulse Width Modulation (SVPWM), Sinusoidal Pulse Width Modulation (SPWM) and Third Harmonic Injection Pulse Width Modulation (THIPWM) using  Matlab/Simulink. This work employs a step by step approach for implementing the switching schemes. This allows for modifying the parameters of the algorithm in a simple way for analysis. Harmonic analysis of the inverter output voltages is performed using the Fast Fourier Transform (FFT) and Total Harmonic Distortion (THD) calculations are made. The analysis of the inverter output voltages show that the harmonic distortion in the SVPWM waveform is less than both SPWM and THIPWM.   Keywords: SVPWM, SPWM, THIPWM, space vector, segments, total harmonic distortionCite this Article Michael Opare Atakora, Arbin Ebrahim, Ji Hyun Lee.
