TRANSFORMER
Document Type and Number:
Japanese Patent JP2017220515
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an easy-to-manufacture and compact transformer, in which leakage inductance is reduced.SOLUTION: In a transformer having a laminated structure ST where multiple coils are laminated via insulating layers, the laminated structure ST consists of a primary coil lamination CL1 constituted of multiple primary coil layers WL1 connected in parallel with each other, and a secondary coil lamination CL2 constituted of multiple secondary coil layers WL2 connected in parallel with each other. The primary coil layer is placed on the outermost layer in the laminated structure, and between at least two layers in the multiple secondary coil layers. The primary coil layer is constituted of multiple primary coils WW1 connected in parallel with each other, and the secondary coil layer is constituted of one or more secondary coils WW2 thicker than the primary coil.SELECTED DRAWING: Figure 3
