Abstract:
(EN) When three-phase AC voltages (Vi1-Vi3) from a commercial AC power supply (51) become abnormal, a control circuit (6) of an uninterrupted power supply device applies an off-command signal to first to third switches (1a-1c) and allows first to third power converters (2a-2c) to output first to third DC currents, respectively, to quickly turn off the first to third switches (1a-1c). In this case, the polarities of the first to third DC currents are the same as the polarities of currents (Is1-Is3) flowing through the first to third switches (1a-1c), respectively, and the sum of the values of the first to third DC currents is zero.
(FR) Lorsque des tensions de courant alternatif triphasé (Vi1 à Vi3) provenant d'une alimentation électrique en courant alternatif commerciale (51) deviennent anormales, un circuit de commande (6) selon l'invention d'un dispositif d'alimentation électrique sans coupure applique un signal de commande d'arrêt aux premier à troisième commutateurs (1a à 1c) et permet aux premier à troisième convertisseurs électriques (2a à 2c) d'émettre des premier à troisième courants continus, respectivement, pour désactiver rapidement les premier à troisième commutateurs (1a à 1c). Dans ce cas, les polarités des premier à troisième courants continus sont les mêmes que les polarités des courants (Is1 à Is3) circulant par les premier à troisième commutateurs (1a à 1c), respectivement, et la somme des valeurs des premier à troisième courants continus est nulle.
(JA) 無停電電源装置の制御回路(6)は、商用交流電源(51)からの三相交流電圧(Vi1~Vi3)が異常になった場合は、第1~第3のスイッチ(1a~1c)にオフ指令信号を与えるとともに、第1~第3の電力変換器(2a~2c)からそれぞれ第1~第3の直流電流を出力させて第1~第3のスイッチ(1a~1c)を迅速に消弧させる。このとき、第1~第3の直流電流の極性はそれぞれ第1~第3のスイッチ(1a~1c)に流れている電流(Is1~Is3)の極性と同じであり、第1~第3の直流電流の値の和は0である。
