This paper proposes the speed control of Induction motor using positive output super lift Luo converter circuit. In the conventional method, the input of the inverter is derived from buck, boost or buck-boost converter which has the limitation over the DC link voltage level and complexity of control circuit. The proposed method uses positive output super lift Luo converter at the front end which boost up the DC link voltage level in a wide range and also the control only in the DC- DC converter instead of Inverter which leads to prevention of Electromagnetic torque ripple and Common mode voltage stress. Super-lift Luo-converters are popular for high output voltage application for years. They have very high voltage transfer gains in geometric progression on stage-by-stage. The proposed system uses PI controller which is highly preferable for industrial applications The simulation is conceded out by MATLAB/SIMULINK software.
