Abstract
Induction motors are widely used in industry due to their promising performance. Majority of induction motors are used in inverter based drives in industrial setups. Efforts are being put in the fault analysis of induction motors. Most of the analysis available in literature discusses the failure of electronic components like power MOSFET, optocoupler failure, failure of pulse generation card etc. This research work is a continuation of fault analysis studies of an inverter fed induction motor drives under different fault conditions. This paper presents the effect of dc link capacitor open circuit on the performance of inverter fed induction motor. Effect on stator current, inverter output, the speed and torque of the motor are particularly studied in this paper. The faults in the DC link is generally not that common but there is always a chance of capacitor failure. The simulated results presented in this paper can augment the efforts for the reliability enhancement of induction motor drives.
