Indirect field oriented control of induction motor with 3-level and 5-level inverter

Abstract

Different methods have been proposed for controlling the induction motor drives .however, based on applications and machine ratings variety of methods have been reported in the literatures. The field oriented control strategies can be remarkably used for high performance ac drives. For improving the dynamic performance of induction motor drive, indirect field oriented control method has widely accepted for improved dynamic performance of induction motor drive. This paper presents indirect field oriented control (IFOC) fed induction motor drive with multilevel inverter topology. Comparison of three levels and five level inverter is also carried out. It can be seen that a five level inverter topology is a more stable and optimum performance can be achieved.
