Design and evaluation of voltage measurement-based sectoral diagnosis method for inverter open switch faults of permanent magnet synchronous motor drives PROJECT TITLE : Design and evaluation of voltage measurement-based sectoral diagnosis method for inverter open switch faults of permanent magnet synchronous motor drives ABSTRACT : A sectoral diagnosis methodology for open switch faults of inverter-fed permanent magnet synchronous motor (PMSM) drives have been described. The proposed diagnosis method defines separate residuals for each of the six switches as a sectoral average of the difference between a reference and measured pole voltage rather than direct use of the instantaneous difference, that has varying AC amount among one cycle of rotation. How to see plausible thresholds is described and therefore the effectiveness and limitation of the proposed methodology are analysed. Many sets of experimental results validate the detection and isolation capability of the proposed methodology. Did you like this research project?
