摘要:与传统星接绕组电机驱动系统相比,采用双逆变器供电的开放绕组电机驱动系统具有高母线电压利用率、更好的容错能力等优点,在电动汽车、电力牵引等领域具有良好的应用前景。但由于三相绕组中性点被拆开,导致系统中存在潜在的零序电流问题,零序电流会增加逆变器容量和系统损耗,甚至使系统无法运行。为消除系统零序电流,本文提出采用不产生共模电压的开关组合进行SVPWM调制,从而抑制系统的共模电压以及由此引起的零序电流。最后通过仿真和实验验证了这种方法的可行性。
关键词:开放绕组电机;双逆变器;共模电压;SVPWM
Abstract: Compared with traditional star connected winding motor, openend winding motor fed by the duel inverter has the advantages of high voltage rate, better fault tolerance, and so on, and therefore it has a good application prospect in the field of electrical vehicle, electrical traction. But since the neutral point of three winding is apart, the potential zerosequence current in the openend winding drive system has to be considered since it causes high capacity and system loss. In order to eliminate the system zerosequence current, a SVPWM modulation using the switch combination without commonmode voltage was investigated in this paper, and the commonmode voltage and zerosequence current can be suppressed. Finally, the method was verified by simulations and experiments.
Key words:  openend winding motor; dual twolevel inverter; commonmode voltage; SVPWM
