Abstract :
In this paper, the output voltage harmonics of three-phase voltage source inverter is investigated by simulation and experimentation. Several main factors which influence harmonics elimination also be discussed. In the precondition that inverter´s hardware topological can´t be transformed, a harmonic restrain method based on inverter output side passive filter has been analyzed in the paper. In the end, a new method of harmonic elimination based on induction parameter identification is proposed. The method can be used in space-vector pulse width modulation (SVPWM) control techniques in order to improve the power factor of the drive and to weaken the injected low-order harmonics to the induction motor
