Abstract
Three-phase induction motor drive systems face significant susceptibility to critical failures arising from open switch faults within the power electronic converter. Implementing monitoring and early fault detection mechanisms for such occurrences not only enhances system reliability but also ensures the safe and uninterrupted operation of the motor drive system. This study introduces an innovative real-time open switch fault detection technique for voltage source inverters fed induction motor drives, leveraging motor stator current analysis. The method aims to track maximum and minimum values of current signals over one cycle. Unlike many current signal-based approaches that require modifications to be integrated with various drive systems, the proposed method operates independently of motor ratings, motor parameters, current levels, and thresholds. Additional characteristics of this approach include simplicity, low computational demands, and fast fault detection capabilities. Both MATLAB simulations and experimental evaluations validate the effectiveness of the proposed fault detection method across various test scenarios
