Abstract
PURPOSE:To find degradation of a smoothing circuit in early stage, by comparing an output from the smoothing circuit with a stabilized DC voltage. CONSTITUTION:Pulsating input immediately after rectification is smoothed through a smoothing circuit 1 then stabilized through a voltage stabilizing circuit 2 and outputted. Output voltage from the smoothing circuit 1 is compared with an output voltage from the voltage stabilizing circuit 2 in a comparator 4, and when the difference is high, an alarm is outputted from the comparator 4. Consequently, degradation of the smoothing circuit 1 can be judged before ripples appear in the output from the voltage stabilizing circuit 2.
