Abstract

PURPOSE: To prevent a fault from occurring by detecting the highest ripple voltage of the DC output voltage of a smoothing circuit and outputting an alarm signal.
CONSTITUTION: The output voltage (b) of the smoothing circuit 1 is inputted to a DC voltage stabilizing circuit 1, which outputs a stabilized DC output voltage (c). A pulsating input voltage (a) is inputted to the smoothing circuit 1. In this case, a ripple voltage detecting circuit 2 which detects the ripple of the output voltage (b) of the smoothing circuit is provided. When, the variation of the ripple of the output voltage (b) is detected to detect the deterioration state of the smoothing circuit 1, and the alarm signal (b) is outputted at the time of a last deterioration state.
