Abstract
(EN) According to the present invention, when a storage battery (92) is charged: a switch (SW1) is energized; a first step-up chopper circuit, a second step-up chopper circuit, and a totem pole bridgeless PFC that are connected in parallel are operated in an interleaving manner; and an alternating current voltage inputted from an alternating current input terminal (PAC1) is converted into direct current and outputted from a direct current output terminal (PDC). When alternating current is outputted using an alternating current output terminal (PAC2), the switch (SW1) is made conductive, a direct current voltage from the storage battery (92) is converted into alternating current using the totem pole bridgeless PFC, and output from the alternating current output terminal (PAC2).
(FR) Selon la présente invention, lorsqu'une batterie rechargeable (92) est chargée : un commutateur (SW1) est excité ; un premier circuit hacheur élévateur, un second circuit hacheur élévateur et un circuit correcteur de facteur de puissance (PFC) à architecture totem-pole sans pont qui sont connectés en parallèle sont actionnés de manière entrelacée ; et une tension alternative entrée à partir d'une borne d'entrée de courant alternatif (PAC1) est convertie en courant continu et délivrée en sortie à partir d'une borne de sortie de courant continu (PDC). Lorsqu'un courant alternatif est délivré en sortie à l'aide d'une borne de sortie de courant alternatif (PAC2), le commutateur (SW1) est mis à l'état passant, une tension continue provenant de la batterie rechargeable (92) est convertie en courant alternatif à l'aide du circuit correcteur de facteur de puissance à architecture totem-pole sans pont et délivrée en sortie à partir de la borne de sortie de courant alternatif (PAC2).
(JA) 蓄電池(92)の充電時は、スイッチ(SW1)を導通し、並列に接続された第1の昇圧チョッパ回路、第2の昇圧チョッパ回路、および、トーテムポールブリッジレスPFCをインターリーブ動作させ、交流入力端子(PAC1)から入力された交流電圧を直流に変換し、直流出力端子(PDC)から出力する。交流出力端子(PAC2)を用いた交流出力時には、スイッチ(SW1)を導通し、トーテムポールブリッジレスPFCを用いて、蓄電池(92)からの直流電圧を交流に変換し、交流出力端子(PAC2)から出力する。
