| Summary: | The identification of faults in voltage source
inverter is highly required to ensure the reliability of the
inverter. Early detection of the faults can greatly assist in
maintenance of the system by avoiding possibly harmful damage
borne out. This paper presents the analysis of short-circuit
switches fault of voltage source inverter (VSI) using time
frequency distribution (TFD). The TFD which is spectrogram
represents current signal of the VSI in time-frequency
representation (TFR) that provides temporal and spectral
information of the signal. From the TFR, parameters of the
signal are estimated such as average current, root mean square
(RMS), total harmonic distortion (THD), total waveform
distortion (TWD) and total non-harmonic distortion (TnHD).
The results shows that the analysis using spectrogram gives
information of the current signal of the VSI to identify shortcircuit
switches |
