摘　　要：针对三相四桥臂逆变器控制系统,基于旋转坐标变换建立了系统模型,提出了一种正负零序分量解耦的控制方法,该方法可以减小三相不平衡负载下的输出电压不平衡度,并且对3D SVPWM发波方式做了简化,使得更有利于工程化实现。通过仿真和实验结果验证了该方法的正确性。A control method for decoupling positive negative and zero sequence components used in three-phase four-leg inverter control system was proposed by rotating coordinate transformation,the unbalance of output voltage of three-phase unbalanced load can be decreased by the novel method,and the 3DSVPWM wave generation mode was simplified,which was more conducive to engineering implementation.The simulation and experimental results are demonstrated to verify the validity of the novel method.
