Abstract:
This paper focuses on finding a novel strategy for reconstructing induction motor phase currents from the DC-link current of two-level voltage source inverters. The main problems are presented and different PWM techniques include SVPWM, NSPWM, AZSPWM and RPWM(RPP) are compared in this paper are discussed. RPP strategy is proved that it can be effectively reduce the invalid regions both around zero voltage and near active-vectors and suite for proposed use. And the influence of the EMI during reconstructing phase current also mentioned in this paper. Experiment result confirms the validity of the new method. © 2010 IEEE.
