摘　　要：针对不平衡和非线性负载采用了一种三相四桥臂拓扑结构,并提出了一种内模原理和空间矢量相结合的控制策略。建立了三相四桥臂逆变器在空间矢量静止坐标系下的数学模型,通过分析四桥臂逆变器的控制规律,将逆变器进行解耦控制。该方法与其他控制方法相比应用方便、参数整定灵活;仿真和试验验证了该控制方案的正确性与可行性。A three-phase four-leg topology was introduced for unbalanced and nonlinear loads.Besides,a novel control scheme based on internal model and SVM was presented.The mathematical model of inverter was built in the αβγ coordinate system and decoupling control model of the whole system was established by analyzed the control law for four-leg inverter.The method was simple and flexible.The simulation and experiment verified that the scheme could work well with fast response,highly accurate steady output and less probability of deformation.
