TY - JOUR A2 - Liu, Qiang AU - Cherif, Bilal Djamal Eddine AU - Bendiabdellah, Azeddine PY - 2018 DA - 2018/03/11 TI - Detection of Two-Level Inverter Open-Circuit Fault Using a Combined DWT-NN Approach SP - 1976836 VL - 2018 AB - Three-phase static converters with voltage structure are widely used in many industrial systems. In order to prevent the propagation of the fault to other components of the system and ensure continuity of service in the event of a failure of the converter, efficient and rapid methods of detection and localization must be implemented. This paper work addresses a diagnostic technique based on the discrete wavelet transform (DWT) algorithm and the approach of neural network (NN), for the detection of an inverter IGBT open-circuit switch fault. To illustrate the merits of the technique and validate the results, experimental tests are conducted using a built voltage inverter fed induction motor. The inverter is controlled by the SVM control strategy.
