Title:
PLANAR TRANSFORMER EMPLOYING INSULATING STRUCTURE FOR PERFORMANCE IMPROVEMENT
Document Type and Number:
WIPO Patent Application WO/2020/230960
Kind Code:
A1
Abstract:
A planar transformer employing an insulating structure for performance improvement according to an embodiment of the present invention comprises: a pair of ferrite cores (110) including an upper core (110-1) and a lower core (110-2); a printed circuit board (120), which is disposed between the pair of ferrite cores (110), one end of which has a primary via hole (121) electrically connecting primary coil patterns, and the other end of which has a secondary via hole (123) electrically connecting secondary coil patterns; an insulating block (130-1) for receiving one side of the pair of ferrite cores (110); and an insulating base (130-2) disposed in the pair of ferrite cores (110) and fittedly coupled to the insulating block (130-1), wherein the insulating block (130-1) and the insulating base (130-2) receive a partial region of the printed circuit board (120) at one side at which the secondary via hole (123) is disposed.
