This paper investigates the fault tolerant control strategies for a three to five-phase dual matrix converter fed open-end load system. There are two three to five phase matrix converter at both the ends of the load. In healthy condition both the matrix converters are sharing the load according to their modulation index. After the occurrence of an open-circuit fault in one of the matrix converter,...
This paper proposes an effective approach to detect, isolate, and identify fault severity and post fault operation of permanent magnet synchronous motors (PMSM) in the presence of stator winding turn fault. The paper proposes fault tolerant operation of PMSM under post condition with stator winding turn fault by using grounded neutral point through controllable impedance using artificial neural network...
A method for fault detection and diagnosis of stator inter-turn short circuits and unbalanced supply voltages for three phase induction machines is presented. The method is based on the analysis of the ratio of third harmonic to fundamental FFT magnitude component of the three-phase stator line current and supply voltage to detect different insulation failure percentages at different load conditions...
