Abstract :
A simplified space-vector pulse width modulation (SVPWM) algorithm for back-to-back three-level converter is analyzed in this paper. Also, a novel virtual flux control strategy and a hybrid rotor flux observer are proposed in the following. These algorithms are put into used in a back-to-back mine hoist control system for induction motor. The experiment results verified the effectiveness of the algorithms and good dynamic and static performance under the proposed control strategy in field.
