Analysis of Induction Motor Drive Systems

Abstract

In industry, the induction machine, particularly the cage rotor type, is most typically employed for variable speed applications. Adjustable speed drives use back-to-back AC to DC and DC to AC conversion to alter the speed. This conversion procedure introduces harmonics and reduces power factor at the supply end. It is now more important than ever to design and build a three-phase induction motor drive with higher power quality. A full report on the converter topologies is used for Power Factor Correction at the input side to eliminate harmonics and enhance power factor at the supply side. So the main aim of this study is to improving power quality by raising power factor at input side of an electric drive, hence lowering losses and boosting efficiency.
