Abstract:
(EN) This uninterruptible power supply device is configured such that, in an inverter power supply mode and a bypass power supply mode, respective phase differences between first to third carrier wave signals (CS1-CS3) for a converter (1) and fourth to sixth carrier wave signals (CS4-CS6) for an inverter (2) are set to 180 degrees, and, in an overlap power supply mode, the respective phase differences between the first to third carrier wave signals and the fourth to sixth carrier wave signals are set to 0 degrees. Thus, a zero-phase current (I01, I02) and a circulating current (ICL) can be reduced.
(FR) La présente invention concerne un dispositif d'alimentation électrique sans coupure qui est configuré de telle sorte que, dans un mode d'alimentation électrique d'onduleur et un mode d'alimentation électrique de dérivation, des différences de phase respectives entre des premier à troisième signaux d'onde porteuse (CS1-CS3) pour un convertisseur (1) et des quatrième à sixième signaux d'onde porteuse (CS4-CS6) pour un onduleur (2) sont définies à 180 degrés, et, dans un mode d'alimentation électrique de chevauchement, les différences de phase respectives entre les premier à troisième signaux d'onde porteuse et les quatrième à sixième signaux d'onde porteuse sont définies à 0 degrés. Ainsi, un courant à phase nulle (I01, I02) et un courant de circulation (ICL) peuvent être réduits.
(JA) この無停電電源装置では、インバータ給電モードおよびバイパス給電モード時には、コンバータ(1)用の第1~第3の搬送波信号(CS1~CS3)とインバータ(2)用の第4~第6の搬送波信号(CS4~CS6)の位相差をそれぞれ180度にし、オーバーラップ給電モード時には、第1~第3の搬送波信号と第4~第6の搬送波信号との位相差をそれぞれ0度にする。したがって、零相電流(I01,I02)および循環電流(ICL)を低減できる。
