Abstract

A fault diagnostic method of 24-pulse uncontrolled diode rectifiers based on the voltage waveform analysis was proposed. The voltage waveform analytic expressions of individual diode running under normal and fault conditions were derived in detail. The analytic results are consistent with the simulation model and reveal the characteristics of the voltage waveform of the rectifier diodes. By utilizing voltage dividers and isolated amplifiers, the voltage waveform of individual diode can be measured by the microcontroller. According to the characteristic values calculated by the fault characteristic function, the fault diode can be located on line. The experimental results are in agreement with theoretical analysis and demonstrate the effectiveness of the method, which is of great value to improve the reliability of equipments.
