Abstract:
(EN) When a first voltage detector (4a) develops a fault, a control circuit (7) of an uninterruptable power supply device controls an inverter (3) in synchronization with the output signal (VI2D) of a second voltage detector (4b), matches the phase of a two-phase AC voltage (VO1, VO2) outputted from the inverter (3) with the phase of a two-phase AC voltage (VI1, VI2) supplied from a commercial AC power supply (51), and subsequently switches on a semiconductor switch pair (S9, S10) and a bypass switch pair (S7, S8). Accordingly, even if the first voltage detector (4a) develops a fault, a two-phase AC voltage can be supplied to a load (53) without instantaneous interruption.
(FR) L'invention concerne un dispositif d’alimentation électrique ininterruptible. Selon l'invention, lorsqu'un premier détecteur de tension (4a) développe un défaut, un circuit de commande (7) d'un dispositif d'alimentation ininterruptible commande un onduleur (3) en synchronisation avec le signal de sortie (VI2D) d'un deuxième détecteur de tension (4b), fait correspondre la phase d'une tension alternative biphasée (VO1, VO2) délivrée par l'onduleur (3) avec la phase d'une tension alternative biphasée (VI1, VI2) fournie par une alimentation électrique en courant alternatif du commerce (51), et bascule ensuite sur une paire de commutateurs à semiconducteur (S9, S10) et une paire de commutateurs de dérivation (S7, S8). Par conséquent, même si le premier détecteur de tension (4a) développe un défaut, une tension alternative biphasée peut être fournie à une charge (53) sans interruption instantanée.
(JA) 無停電電源装置の制御回路(7)は、第1の電圧検出器(4a)が異常になった場合は、第2の電圧検出器(4b)の出力信号(VI2D)に同期してインバータ(3)を制御し、インバータ(3)から出力される二相交流電圧(VO1,VO2)の位相を商用交流電源(51)から供給される二相交流電圧(VI1,VI2)の位相に一致させた後に、半導体スイッチ対(S9,S10)およびバイパススイッチ対(S7,S8)をオンさせる。したがって、第1の電圧検出器(4a)が異常になった場合でも、負荷(53)に対して二相交流電圧を無瞬断で供給することができる。
