Title (EN) POWER CONVERSION DEVICE, MOTOR MODULE, AND ELECTRIC POWER STEERING DEVICE
(FR) DISPOSITIF DE CONVERSION DE PUISSANCE, MODULE MOTEUR ET DISPOSITIF DE DIRECTION ASSISTÉE ÉLECTRIQUE
(JA) 電力変換装置、モータモジュールおよび電動パワーステアリング装置
Abstract:
(EN) A power conversion device, provided with: a first inverter 100A; a second inverter 100B; a first control circuit and second control circuit 410A, 410B for controlling the first and second inverters; and a drive circuit 440 for supplying a control signal for switching on a low-side switch element of the first inverter to the low-side switch element when a fault occurs on the first inverter side, and supplying a control signal for switching on a low-side switch element of the second inverter to the low-side switch element when a fault occurs on the second inverter side. When a fault occurs on the second inverter side, a first power supply voltage generated on the first inverter side is fed to the drive circuit, and when a fault occurs on the first inverter side, a second power supply voltage generated on the second inverter side is fed to the drive circuit.
(FR) L'invention concerne un dispositif de conversion de puissance comprenant : un premier onduleur 100A ; un second onduleur 100B ; un premier circuit de commande et un second circuit de commande 410A, 410B servant à commander les premier et second onduleurs ; et un circuit de pilotage 440 servant à appliquer un signal de commande de commutation sur un élément de commutation côté bas du premier onduleur à l'élément de commutation côté bas lorsqu'un défaut se produit du côté premier onduleur, et à appliquer un signal de commande de commutation sur un élément de commutation côté bas du second onduleur à l'élément de commutation côté bas lorsqu'un défaut se produit du côté second onduleur. Lorsqu'un défaut se produit du côté second onduleur, une première tension d'alimentation électrique générée du côté premier onduleur est appliquée au circuit de pilotage, et lorsqu'un défaut se produit du côté premier onduleur, une seconde tension d'alimentation électrique générée du côté second onduleur est appliquée au circuit de pilotage.
(JA) 電力変換装置は、第１インバータ１００Ａと、第２インバータ１００Ｂと、第１および第２インバータを制御する第１および第２制御回路４１０Ａ、４１０Ｂ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に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に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、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。
