Design of Active Filter to Minimize the Effect of Long Cables On Inverter Fed Induction Motor

M.Umapriya, K.Kanchana, V.Rajini

Inverter fed Induction motor drive systems are widely used in industrial applications because of their energy efficiency and flexible control. The motor is subjected to over voltages due to long cable length, fast rise/fall time of inverter pulses and impedance mismatch between cable and motor. The overvoltage causes premature failure of the motor insulation. The proposed active filter reduces the voltage surge and increase rise/fall time of the voltage at the motor terminals. In this paper an active filter is designed and simulated for 3-phase PWM Inverter Fed 1-hp Induction Motor drive using Simulink for different cable lengths.
