摘要：This paper proposes an economic approach for 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 limitations over the DC link voltage level, complexity of control circuit and cost involved in system design. The proposed method uses positive output super lift Luo converter at the front end which boosts up the DC link voltage level in a wide range. The speed control of the induction motor is attained by controlling the firing angle of positive output super lift Luo converter instead of Inverter which leads to prevention of motor terminals from Common mode voltage stress. Super-lift Luo-converters are popular for high output voltage application over 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.
