Title
(EN) INSULATION TRANSFORMER, INSULATION MODULE, AND GATE DRIVER
(FR) TRANSFORMATEUR D'ISOLATION, MODULE D'ISOLATION ET CIRCUIT D'ATTAQUE DE GRILLE
(JA) 絶縁トランス、絶縁モジュールおよびゲートドライバ
Abstract
(EN) The insulation transformer comprises: an insulation layer; and a transformer which has first and second coils embedded in the insulation layer. The first and second coils are arranged so as to oppose each other in the thickness direction of the insulation layer. The first and second coils include non-overlapping parts which dot not overlap each other in the thickness direction of the insulation layer.
(FR) L'invention concerne un transformateur d'isolation comprenant : une couche d'isolation ; et un transformateur qui a des première et seconde bobines incorporées dans la couche d'isolation. Les première et seconde bobines sont agencées de manière à s'opposer l'une à l'autre dans le sens de l'épaisseur de la couche d'isolation. Les première et seconde bobines comprennent des parties non chevauchantes qui ne se chevauchent pas dans la direction de l'épaisseur de la couche d'isolation.
(JA) 絶縁トランスは、絶縁層と、絶縁層に埋め込まれた第1コイルおよび第2コイルを有するトランスと、を有する。第1コイルおよび第2コイルは、絶縁層の厚さ方向において対向配置されている。第1コイルおよび第2コイルは、絶縁層の厚さ方向において互いに重ならない非重なり部を含む。
