A Noval Method of Single Phase to Three Phase Cyclo Converter for Three Phase Induction Motor Drive

Abstract

This paper present the study on analysis of speed of induction motor when the motor is made to run on different loads torque. fed by single phase to three phase cyclo converter.. Normally, constant voltage constant frequency single phase AC or three phase AC is used. However in some rural areas, only a single phase utility is available, so it became necessary to convert single phase supply to three phase supply to run three phase induction motors. For this purpose, cyclo converter model is patterned by MATLAB/SIMULINK SOFTWARE to convert single phase supply to three phase supply. Converter model employs only six IGBT so the resulting Cyclo converter-motor drive system is cheap and compact, As we know that the rating of the machine increases with the increase in number of phase .eg. output of three phase motor is 1.5 times the output of a single phase motor of same size. therefore it is beneficial to use three phase induction motor instead of single phase induction motor for low industrial applications
