    • A self-excited DC-DC converter comprises a switching element that chops a direct-current input voltage; a smoothing circuit that smoothes the chopped voltage to generate a DC output voltage; a switching control signal generation circuit that generates a switching control signal for the on/off control of the switching element by comparing a feedback voltage of the output voltage and a comparison voltage; an output correction circuit that adjusts the comparison voltage according to an error between the feedback voltage and the reference voltage and, when the output current is in the overcurrent state, reduces the level of the comparison voltage; an overcurrent protection signal generation circuit that, when the output current is in an overcurrent state, generates an overcurrent protection signal for turning off the switching element regardless of the switching control signal; and a delay circuit that delays the overcurrent protection signal. Also, a switching control circuit is provided therein.

    • A peak detecting section 121 detects the maximum values (peaks) of frequency distributions, at intervals of unit times, from the wavelet intensity signal output from an intensity computing section 113. More specifically, giving attention to frequency distributions of the wavelet intensity signal as the transform result obtained by a signal converting section 110 at predetermined time intervals, the peak detecting section 121 detects the peaks (maximum values) of the frequency intensity distributions at intervals of unit times (predetermined time intervals). Changes in various frequency features over time which are contained in the time-series signal obtained by a wavelet transform of the time-series signal can be quantitatively grasped more accurately.
