Design and implementation of SVPWM based Voltage Source Converters with Extended Selective Harmonic Compensation

Abstract

 The rapid development of high switching frequency power electronics in the past decade leads towards wider application of voltage source converters in AC power generation. Therefore, this prompts the need for a modulation technique with less total harmonic distortion, fewer 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) techniques because of their easier digital realization and better DC bus utilization. The space vector control algorithm in VSC provides different functions such as reactive power compensation for Power factor correction, Harmonic Elimination, Load balancing for both linear and non-linear loads. Also, selective harmonic compensation (SHC) is possible in order to avoid possible resonances at given frequencies. It can be implemented by using MATLAB/SIMULINK Software.
