Title (EN) INVERTER CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE D'ONDULEUR
(JA) インバータ制御装置
Abstract:
(EN) According to the present invention, fail-safe control is properly performed even when one of switching elements of an inverter is off-circuited. This inverter control device (20) controls an inverter (10) that is connected to a direct current power source (11) and to an alternating current rotary electric machine (80) and converts power between a direct current and a multi-phase alternating current. In an off-failure state (SPH_OFF) in which one of switching elements (3) constituting the inverter (10) is always turned off, the inverter control device (20) performs, torque reduction control (ZTQ) for reducing the torque of the rotary electric machine (80) by controlling switching of the switching elements (3), or deceleration control for outputting torque in a direction opposite to the rotating direction of the rotary electric machine (80).
(FR) Selon la présente invention, une commande à sécurité intégrée est correctement effectuée même lorsque l'un des éléments de commutation d'un onduleur est hors circuit. Ce dispositif de commande d'onduleur (20) commande un onduleur (10) qui est connecté à une source d'alimentation en courant continu (11) et à une machine électrique rotative à courant alternatif (80), et convertit la puissance entre un courant continu et un courant alternatif polyphasé. Dans un état de coupure (SPH_OFF) dans lequel l'un des éléments de commutation (3) constituant l'onduleur (10) est toujours éteint, le dispositif de commande d'onduleur (20) effectue une commande de réduction de couple (ZTQ) pour réduire le couple de la machine électrique rotative (80) en commandant la commutation des éléments de commutation (3), ou une commande de décélération pour fournir un couple dans une direction opposée à la direction de rotation de la machine électrique rotative (80).
(JA) インバータのスイッチング素子の1つがオフ故障していても、適切にフェールセーフ制御を行う。直流電源(11)に接続されると共に交流の回転電機(80)に接続されて直流と複数相の交流との間で電力を変換するインバータ(10)を制御するインバータ制御装置(20)は、インバータ(10)を構成するスイッチング素子(3)の内の1つが常時オフ状態となるオフ故障した状態(SPH_OFF)で、スイッチング素子(3)をスイッチング制御して、回転電機(80)のトルクを減少させるトルク減少制御(ZTQ)、又は、回転電機(80)の回転方向とは逆方向のトルクを出力させる減速制御を実行する。
