Abstract:
(EN) A power conversion device 1000 comprises: a first inverter 100A; a second inverter 100B; a drive circuit 440 for applying, to a low-side switch element of the first inverter, a control signal for turning on the low-side switch element when a failure has occurred on the first inverter side, and applying, to the low-side switch element of the second inverter, the control signal for turning on the low-side switch element when a failure has occurred on the second inverter side; and a control circuit 410. When failure occurs on the second inverter side, a first power supply voltage generated on the first inverter side is supplied to the drive circuit, and when failure occurs on the first inverter side, a second power supply voltage generated on the second inverter side is supplied to the drive circuit.
(FR) La présente invention concerne un dispositif de conversion de courant (1000) qui comprend : un premier onduleur (100A) ; un second onduleur (100B) ; un circuit d'attaque (440) destiné à appliquer, à un élément de commutation côté inférieur du premier onduleur, un signal de commande permettant d'activer l'élément de commutation côté inférieur lorsqu'une défaillance s'est produite sur le côté du premier onduleur, et appliquer, à l'élément de commutation côté inférieur du second onduleur, le signal de commande permettant d'activer l'élément de commutation côté inférieur lorsqu'une défaillance s'est produite sur le côté du second onduleur ; et un circuit de commande (410). Lorsqu'une défaillance se produit sur le côté du second onduleur, une première tension d'alimentation électrique générée sur le côté du premier onduleur est fournie au circuit d'attaque, et lorsqu'une défaillance se produit sur le côté du premier onduleur, une seconde tension d'alimentation électrique générée sur le côté du second onduleur est fournie au circuit d'attaque.
(JA) 電力変換装置1000は、第1インバータ100Aと、第2インバータ100Bと、第1インバータ側で故障が発生したとき、第1インバータのローサイドスイッチ素子をオンする制御信号をローサイドスイッチ素子に与え、第2インバータ側で故障が発生したとき、第2インバータのローサイドスイッチ素子をオンする制御信号をローサイドスイッチ素子に与える駆動回路440と、制御回路410とを備える。第2インバータ側で故障が発生したとき、第1インバータ側で生成される第1電源電圧が駆動回路に供給され、かつ、第1インバータ側で故障が発生したとき、第2インバータ側で生成される第2電源電圧が駆動回路に供給される。
