ABSTRACT

The faulty performance of six diodes three phase rectifier is studied under one and two simultaneous open-diodes conditions. This rectifier is feeding a resistive load. The rectifier three phases currents zero harmonic components and their maximum and minimum values are used as diagnostic indices. A knowledge algorithm is based to get information on which IGBT is in open-switch fault condition. This algorithm testing shows that the system could not only detect the openswitch fault, but also identify the faulty switches. Presented simulation results confirm the effectiveness of the proposed methodology.

Keywords: Six Diodes Three Phase Voltage Rectifier, Fault Diagnosis, Alternative Current, Zero Harmonic Component, Min and Max Value
