摘　　要：文章对三相四桥臂逆变器的控制系统进行设计,建立了基于对称分量法和双同步旋转d-q坐标系的双环控制结构,电压外环和电流内环均采用前馈解耦的控制策略,使三相四桥臂逆变器具有带不平衡负载的能力。最后,以1.5 kW三相四桥臂逆变器装置进行实验,实验结果验证了上述方案的正确性和有效性。This paper sets up a double control configuration based on symmetrical components and bisynchronous coordinates. The outside voltage loop and the inside current loop both adopt feedforward decoupling control, thus the three-phase four-leg inverter has the ability to supply unbalanced loads. A 1.5 kW three-phase four-leg inverter has been built and the experiment results validate the operating principle.
