Title:
TRANSFORMER AND POWER SUPPLY APPARATUS FOR LOWERING DISPLACEMENT CURRENT BY MEANS OF CAPACITIVE COUPLING BETWEEN WINDINGS
Document Type and Number:
WIPO Patent Application WO/2021/225354
Kind Code:
A1
Abstract:
The present invention relates to a transformer and power supply apparatus for significantly lowering the effect of noise from the power supply apparatus to the outside through a line by lowering, by using capacitive coupling between windings of the transformer of the power supply apparatus, the sum of capacitive couplings of switching frequency components between a primary side of the transformer of the power supply apparatus and an output winding, and the deviation between products in the sum of the capacitive couplings.
