Title (EN) INVERTER DEVICE
(FR) DISPOSITIF ONDULEUR
(JA) インバータ装置
Abstract:
(EN) Provided is an inverter device that drives an electric motor 2 by generating alternating current voltage from direct current voltage, the inverter device including the following: a smoothing capacitor 3 that mitigates ripple voltage that is superimposed on the direct current voltage; an inverter circuit 4 having a plurality of switching elements 40u-40w, 41u-41w; and a control unit 5 that controls the driving of the plurality of switching elements 40u-40w, 41u-41w of the inverter circuit 4. The control unit 5 controls the driving of the plurality of switching elements 40u-40w, 41u-41w when the smoothing capacitor 3 undergoes an open fault, thereby restricting the current passing through the electric motor 2.
(FR) La présente invention concerne un dispositif onduleur qui entraîne un moteur électrique 2 en générant une tension alternative à partir d'une tension continue. L'onduleur comprend ce qui suit : un condensateur de lissage 3 qui atténue une tension d'ondulation qui est superposée à la tension continue; un circuit onduleur 4 ayant une pluralité d'éléments de commutation 40u-40w, 41u-41w; et une unité de commande 5 qui commande l'excitation de la pluralité des éléments de commutation 40u-40w, 41u-41w du circuit onduleur 4. L'unité de commande 5 commande l'excitation de la pluralité d'éléments de commutation 40u-40w, 41u-41w lorsque le condensateur de lissage 3 présente un état ouvert défectueux, restreignant de cette façon le courant traversant le moteur électrique 2.
(JA) 直流電圧から交流電圧を生成して電動機2を駆動するインバータ装置は、直流電圧に重畳するリップル電圧を抑制する平滑コンデンサ3と、複数のスイッチング素子40u~40w、41u~41wを有するインバータ回路4と、インバータ回路4の複数のスイッチング素子40u~40w、41u~41wの駆動を制御する制御部5と、を含み、制御部5は、平滑コンデンサ3がオープン故障したときに、複数のスイッチング素子40u~40w、41u~41wの駆動を制御することにより、電動機2の通電電流を制限する。
