In this paper, a novel autotransformer based 18-pulse Ac-Dc Converter fed vector controlled induction motor drive is discussed and its Matlab/Simulink model is also given. The procedure for proposed autotransformers shows the flexibility in the design for making it a cost effective replacement suitable for retrofit applications, where presently a six-pulse diode bridge rectifier is used. Using the above designs we can capable to suppress harmonics up to 13th in 18-pulse configuration of the VCIMD. Various simulation results are given for autotransformer and VCIMD in topology C and D. THD analysis at No load and Load is also done. A comparative performance of different ac-dc converters based on eighteen-pulse rectification has also been presented to demonstrate the performance of the proposed AC- DC converter feeding VCIMD.
