Design and Analysis of Novel Dc Link Controller for Induction Motor Drives

Abstract

A control over induction motor (IM) fed by a VSI can be carried out by an active front end topology so as to improve the power factor (PF). Hence, this study analyses the performance of PI controller based AFE topology. This AFE topology comprises single phase rectifier unit and DC- DC converter. Thus, from the results obtained it is proven that the proposed AFE topology is suitable for IM drives and exhibits lesser THD with high PF.
