Abstract

PURPOSE:To eliminate the occurrence of rectification noise produced at a rectifier at the primary side through a transformer by inserting a bypass capacitor between the rectifier and the transformer. CONSTITUTION:The secondary AC voltage generated at a transformer 5 is rectified by a rectifier 6, is smoothed by a capacitor 7, and the current of noise source tending to flow through the secondary coil of the transformer 5 is bypassed via a bypass capacitor 9 by inserting the capacitor 9 between the rectifier 6 and the transformer 5 of a dropper type power source which can produce a DC voltage via a regulator 8. Since the rectification noise of the power source is not produced in the primary side of the transformer merely by adding small amount of parts in this manner, is can be adpated for the noise terminal voltage of the standard stipulated by Japanese Radio Wave Council or the like.
