Title:
PLANAR TRANSFORMER UTILIZING INSULATING STRUCTURE FOR PERFORMANCE IMPROVEMENT
Document Type and Number:
WIPO Patent Application WO/2020/075996
Kind Code:
A1
Abstract:
A planar transformer utilizing an insulating structure for performance improvement according to the present invention is characterized by comprising: a pair of ferrite cores; a printed circuit board which is disposed between the pair of ferrite cores and has primary via-holes on one end thereof and secondary via-holes on the other end thereof, the primary via-holes electrically connecting primary coil patterns, and the secondary via-holes electrically connecting secondary coil patterns; and an insulating block and an insulating base, which accommodate a portion of the ferrite cores and secure an insulating distance between the ferrite cores and the secondary via-holes, wherein the insulating block (130-1) and the insulating base (130-2) are coupled to each other to accommodate the printed circuit board (120). The planar transformer utilizing an insulating structure for performance improvement according to the present invention provides a firm coupling structure and can reduce the overall size of a product, and thus has an advantage in that the performance of the transformer is improved by virtue of the size of the secondary coil patterns being decreased and the resistance value of secondary coils being decreased.
