Abstract: <P>PROBLEM TO BE SOLVED: To provide a degradation diagnostic device for a DC power unit for patterning the change of the output waveform of monitoring object equipment and automatically discriminating the degradation of the DC power unit.  <P>SOLUTION: The degradation diagnostic device for the DC power unit is a means for detecting the ripple component of a DC power supply output voltage, sampling the detected ripple component signal of the DC power supply output voltage at every prescribed interval of time, outputting a plurality of pieces of time-sequential data, computing the short-time Fourier transform thereof, comparing a computed value with a value when the DC power unit is normal and diagnosing degradation on the basis of the compared result, and performs computation after obtaining the average value, variance, skewness and kurtosis of each frequency as a comparison means. Thus, the degradation is reliably and efficiently recognized, a measurement time is shortened, sensitivity to a phenomenon that an abnormality appears in dispersion is improved, the phenomenon that the abnormality appears in bias is determined in a short time, and the sensitivity to the phenomenon that the abnormality appears in spread is improved as well. Thus, such a disadvantage is dissolved that the root mean square value of a DC voltage and the root mean square value of a ripple voltage are hardly influenced even when about a half of the capacity of a smoothing capacitor is consumed and the abnormality cannot be discriminated even when an important component is degraded since conventionally the root mean square value of the DC voltage and the root mean square value of the ripple voltage are detected.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
