Renewable Energy Source Applications in Multilevel Inverter Based Induction Motor Drive Using ANN
G. Sathish Goud | Venkateswarlu Kalimela
Abstract: This paper presents optimized multilevel inverter topology is proposed for a four pole induction motor drive. The open-end winding scheme, the Induction Motor windings are fed from both sides with two two-level inverters (with half the dc-link voltage when compared with conventional NPC inverter) to get a three-level inverter topology. With this concept as the number of levels increases, the inverters have to be cascaded or a conventional multi-level inverters have to be used on both the sides of the Induction Motor winding. This topology has developed by using the advantage of two identical voltage profile winding coils per phase in a four pole induction motor drive using Ann. Further the DC source is replaced by a renewable resource such as solar panels, wind power etc. and DC voltage is obtained. Performance characteristics of three-phase asynchronous motor are analyzed with PV array connected. The method can be easily extended to a multilevel inverter. The proposed concept is verified by using Matlab/Simulink software and the corresponding results are presented.
