Title (EN) MOTOR DRIVE SYSTEM OF ELECTRIC VEHICLE
(FR) SYSTÈME D'ENTRAÎNEMENT DE MOTEUR DE VÉHICULE ÉLECTRIQUE
(ZH) 电动汽车的电机驱动系统
Abstract:
(EN) A motor drive system (10) of an electric vehicle, used for driving an alternating current motor (90) and comprising: a first inverter power module (120) and a second inverter power module (120') disposed in a manner of parallel connection; a direct current input end of the first inverter power module (120) and a direct current input end of the second inverter power module (120') are both electrically connected to an output end of a power battery (30) of the electric vehicle; a first three-phase alternating current output end of the first inverter power module (120) outputs a first three-phase alternating current (U1, V1, W1) to a first three-phase winding (910) of the alternating current motor (90); and a second three-phase alternating current output end of the second inverter power module (120') outputs a second three-phase alternating current (U1', V1', W1') to a second three-phase winding (920) of the same alternating current motor (90). The motor drive system is low in cost, reliable and safe.
(FR) L'invention concerne un système d'entraînement de moteur (10) d'un véhicule électrique utilisé pour entraîner un moteur à courant alternatif (90) et comprenant : un premier module d'alimentation à onduleur (120) et un second module d'alimentation à onduleur (120') disposés à la manière d'une connexion parallèle; une extrémité d'entrée de courant continu du premier module d'alimentation à onduleur (120) et une extrémité d'entrée de courant continu du second module d'alimentation à onduleur (120') sont toutes deux connectées électriquement à une extrémité de sortie d'une batterie d'alimentation (30) du véhicule électrique; une première extrémité de sortie de courant alternatif triphasé du premier module d'alimentation à onduleur (120) fournit un premier courant alternatif triphasé (U1. V1. W1) à un premier enroulement triphasé (910) du moteur à courant alternatif (90); et une seconde extrémité de sortie de courant alternatif triphasé du second module d'alimentation à onduleur (120') fournit un second courant alternatif triphasé (U1', V1', W1') à un second enroulement triphasé (920) du même moteur à courant alternatif (90). Le système d'entraînement de moteur est peu coûteux, fiable et sûr.
(ZH) 一种电动汽车的电机驱动系统(10),用于驱动交流电机(90),包括:并联地设置的第一逆变功率模块(120)和第二逆变功率模块(120');其中,第一逆变功率模块(120)的直流输入端和第二逆变功率模块(120')的直流输入端均电连接电动汽车的动力电池(30)的输出端,第一逆变功率模块(120)的第一三相交流输出端输出第一三相交流电(U1,V1,W1)至所述交流电机(90)的第一三相绕组(910),第二逆变功率模块(120')的第二三相交流输出端输出第二三相交流电(U1',V1',W1')至同一所述交流电机(90)的第二三相绕组(920)。该电机驱动系统成本低、可靠性和安全性好。
