Title (EN) CORE FOR HIGH-FREQUENCY TRANSFORMER, AND MANUFACTURING METHOD THEREFOR
(FR) NOYAU DE TRANSFORMATEUR HAUTE FRÉQUENCE ET SON PROCÉDÉ DE FABRICATION
(JA) 高周波トランス用磁心、及びその製造方法
Abstract: front page image
(EN)This core for a high-frequency transformer has shape formed by a single roll process by winding a Fe-based nanocrystal alloy thin strip (1) that has a roll contact surface (2) and a free surface (3) while interposing an insulating layer (4), characterized in that projections (5) having a crater-form depression are dispersed on the free surface (3) of the Fe-based nanocrystal alloy thin strip (1), and the apexes of the projections (5) are ground and blunted.
(FR)Cette invention concerne un noyau pour un transformateur haute fréquence présentant une forme obtenue par un traitement sur cylindre unique par enroulement d'une bande mince alliée de nanocristal à base de Fe (1) présentant une surface de contact de cylindre (2) et une surface libre (3), tout en interposant une couche isolante (4), caractérisé en ce que des saillies (5) comprenant un creux en forme de cratère sont dispersées sur la surface libre (3) de la bande mince alliée de nanocristal à base de Fe (1) et en ce que les sommets des saillies (5) sont meulées et émoussées.
(JA) 単ロール法によるロール接触面2と自由面3とを有するFe基ナノ結晶合金薄帯1が絶縁層4を介して巻回された形状を有する磁心であって、Fe基ナノ結晶合金薄帯1における自由面3には、クレーター状の窪みを有する突起5が分散すると共に、突起5は、その頂部が研磨され鈍化されていることを特徴とする高周波トランス用磁心である。
