Abstract:
(EN) This power conversion device (101) includes a conversion circuit (1) constituted by a plurality of arm circuits (6) and a bypass circuit (30). The bypass circuit (30) includes a full-wave rectifier circuit (37), a positive side connection arm (36a), and a negative side connection arm (36b). The full-wave rectifier circuit (37) is connected between a plurality of AC connection portions (Nu, Nv, Nw) and a positive side intermediate node (Npd) and between the plurality of AC connection portions (Nu, Nv, Nw) and a negative side intermediate node (Nnd) and configured so that an AC voltage generated at the plurality of AC connection portions (Nu, Nv, Nw) can be output between the positive side intermediate node (Npd) and the negative side intermediate node (Nnd) as a DC voltage. The positive side connection arm (36a) blocks current flowing from a positive side DC terminal (Np) toward the positive side intermediate node (Npd). The negative side connection arm (36b) is connected between the negative side intermediate node and a negative side DC terminal and blocks current flowing from the negative side intermediate node (Nnd) toward the negative side DC terminal (Nn).
(FR) Le dispositif de conversion de puissance (101) de l'invention comprend : un circuit de conversion (1) constitué d'une pluralité de circuits de branchement (6) et d'un circuit de dérivation (30). Le circuit de dérivation (30) comprend un circuit redresseur pleine onde (37), une branche de raccordement côté positif (36a) et une branche de raccordement côté négatif (36b). Le circuit redresseur pleine onde (37) est raccordé entre une pluralité de parties de raccordement CA (Nu, Nv, Nw) et un noeud intermédiaire côté positif (Npd) et entre la pluralité de parties de raccordement CA (Nu, Nv, Nw) et un noeud intermédiaire côté négatif (Nnd), et est configuré de sorte qu'une tension alternative générée au niveau de la pluralité de parties de raccordement CA (Nu, Nv, Nw) puisse être délivrée entre le noeud intermédiaire côté positif (Npd) et le noeud intermédiaire côté négatif (Nnd) en tant que tension continue. La branche de raccordement côté positif (36a) bloque le courant circulant d'une borne CC côté positif (Np) au noeud intermédiaire côté positif (Npd). La branche de raccordement côté négatif (36b) est raccordée entre le noeud intermédiaire côté négatif et une borne CC côté négatif et bloque le courant circulant du noeud intermédiaire côté négatif (Nnd) à la borne CC côté négatif (Nn).
(JA) 電力変換装置(101)は、複数のアーム回路(6)で構成された変換回路(1)とバイパス回路(30)とを含む。バイパス回路(30)は、全波整流回路(37)と、正側接続アーム(36a)と、負側接続アーム(36b)とを含む。全波整流回路(37)は、複数の交流接続部(Nu,Nv,Nw)と正側中間ノード(Npd)と負側中間ノード(Nnd)との間に接続され、複数の交流接続部(Nu,Nv,Nw)に生成される交流電圧を正側中間ノード(Npd)と負側中間ノード(Nnd)との間に直流電圧として出力可能に構成される。正側接続アーム(36a)は、正側直流端子(Np)から正側中間ノード(Npd)の方向の電流を阻止する。負側接続アーム(36b)は、負側中間ノードと負側直流端子との間に接続され、負側中間ノード(Nnd)から負側直流端子(Nn)の方向の電流を阻止する。
