A Study on the Novel Space Vector Based Harmonic Elimination Method of Inverter

인버터 고조파 저감을 위한 새로운 공간벡터 변조기법에 관한 연구

This paper considers the problem of eliminating harmonics in the inverter output waveforms. The approach is based on the minimization of the current harmonics in the induction motor by space vector modulation method. Reference voltage is compensated with injection of controlled current harmonics which are calculated to reduce current harmonics through sampled current harmonic analyzing algorithm. The theoretical analysis is carried out using computer simulation. It is verified that proposed SVM technique could reduce current harmonic component and improve THD.
