Title:
HIGH OUTPUT TRANSFORMER FOR HIGH FREQUENCY
Document Type and Number:
Japanese Patent JP2018190980
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high output transformer for high frequency in which a loss is reduced by suppressing resistance that is generated in a low-voltage high-current side coil.SOLUTION: The present invention relates to a high output transformer for high frequency comprising a primary-side coil 2 and a secondary-side coil 3 including wires wound around different outer peripheral surfaces of a core. A wire 10B (Litz wire) that is provided in a low-voltage high-current side coil 4B in the primary-side coil and the secondary-side coil includes a conductor part and an insulation layer covering an outer periphery of the conductor part. Regarding an outer diameter of the conductor part and an outer diameter of the wire, an outer diameter difference/2 ([outer diameter of wire-outer diameter of conductor part]/2) ranges from 70 to 260 μm, and an outer diameter ratio (outer diameter of conductor part/outer diameter of wire) ranges from 0.48 to 0.84.SELECTED DRAWING: Figure 5
