Title (EN) POWER CONVERTER DEVICE
(FR) DISPOSITIF CONVERTISSEUR DE PUISSANCE
(JA) 電力変換装置
Abstract:
(EN) The present invention provides a power converter device capable of suppressing smoking, burning, and short circuiting even when a fuse melts due to overcurrent and preventing heat emanating from a fuse from reaching a power semiconductor element. A power converter device (1) comprises: a fuse (16) formed in an electrode wire member (13); a fuse resin member (26) covering the fuse (16); and a sealing resin member (25) for sealing a power semiconductor element (14) and the fuse (16) in a housing (30). The fuse (16) comprises: a first upstream part (16a1) having a smaller cross-sectional area than an upstream portion along the direction of electrical current; a second part (16b) having a smaller cross-sectional area than the first upstream part (16a1); and a first downstream part (16a2) having a cross-sectional area greater than the second part (16b) and smaller than a downstream portion.
(FR) La présente invention concerne un dispositif convertisseur de puissance capable de supprimer la fumée, la combustion et les court-circuits même lorsqu'un fusible fond sous l'effet d'une surintensité et empêche la chaleur émanant d'un fusible d'atteindre un élément semi-conducteur de puissance. Un dispositif convertisseur de puissance (1) comprend : un fusible (16) formé dans un élément de fil d'électrode (13) ; un élément de résine de fusible (26) recouvrant le fusible (16 ); et un élément de résine d'étanchéité (25) pour sceller un élément semi-conducteur de puissance (14) et le fusible (16) dans un boîtier (30). Le fusible (16) comprend : une première partie amont (16a1) ayant une aire de section transversale plus petite qu'une partie amont le long de la direction du courant électrique ; une seconde partie (16b) ayant une aire de section transversale plus petite que la première partie amont (16a1) ; et une première partie aval (16a2) ayant une aire de section transversale supérieure à la seconde partie (16b) et inférieure à une partie aval.
(JA) 過電流によりヒューズ部が溶断しても、発煙、焼損、短絡を抑制できると共に、ヒューズ部の発熱が電力用半導体素子に伝達され難くできる電力変換装置を提供する。電力変換装置(1)は、電極配線部材(13)に形成されたヒューズ部(16)と、ヒューズ部(16)を覆うヒューズ樹脂部材(26)と、電力用半導体素子(14)及びヒューズ部(16)を筐体(30)内に封止する封止樹脂部材(25)と、を備え、ヒューズ部(16)は、電流方向に沿って、上流側部分よりも断面積が小さい上流側の第1段目部分(16a1)、上流側の第1段目部分(16a1)よりも断面積が小さい第2段目部分(16b)、及び第2段目部分(16b)よりも断面積が大きく、下流側部分よりも断面積が小さい下流側の第1段目部分(16a2)により構成されている。
