Abstract

PURPOSE:To enable detection of an overcurrent without increasing a surge by connecting a plurality of electrolytic capacitors in parallel to constitute a smoothing electrolytic capacitor and by inserting a DC current transformer into a circuit of one of said electrolytic capacitors. CONSTITUTION:An electrolytic capacitor for smoothing the DC output of a full-wave rectifier 2 is composed of a plurality of parallel-connected electrolytic capacitors 3a-3n. A DC current transformer (DCCT) 6 is inserted into a circuit of the electrolytic capacitor 3a being on the nearest side to the full-wave rectifier 2. Said DCCT6 takes out a current flowing out from the electrolytic capacitor 3a and inputs said current to an overcurrent detector.
