Harmonic elimination of three-phase inverter-fed nonlinear loads

In this study, three-phase voltage source inverter is controlled by space vector pulse width modulation. Three-phase voltage-source inverter output is connected to the three-phase star connected resistive load. Inverter output voltage and the voltage of the harmonic order are analyzed by Matlab/Simulink program. Harmonics caused by the speed of program analysis with low-pass filter are eliminated. This practice is also obtained experimentally. However, in both applications, main harmonic amplitude of inverter output voltage due to speed of analysis and low-pass filter circuit characteristics is observed at the bottom of the reference value. To control harmonic amplitude is applied to synchronous reference control method. This control strategy for both linear and nonlinear loads are applied. Whether this control method to eliminate the desired harmonic, the main harmonic amplitude is kept for the reference value.
