| 摘 要： | 由于H桥可输出±,0三种电平,故级联型结构一层类似于三电平中点箝位(NPC),可采样三电平空间矢量调制(SVM).简化分解算法可将三电平矢量分解为两电平矢量,通过类比左、右桥臂组矢量,可得到适用于级联型三电平逆变器的具体调制算法.为平衡左、右桥臂组开关频率,通过对负电平进行调整,派生出一种调制算法.实验结果验证了这两种三电平SVM应用于级联型结构的有效性,并在开关频率和谐波含量等方面有一定优势. |

| Abstract: | A H-bridge cell can output positive,negative and zero three-level voltages,so one layer of cascaded structure is similar to three-level neutral point clamping(NPC),and three-level space vector modulation(SVM) can be used in it.A 3-level vector can be decomposed to two-level vectors by the simplified algorithm.By comparing with left and right bridges vectors,the modulating algorithms suitable for cascaded multilevel structure are obtained.To balance switching frequencies of left and right bridges,a modulatin... |
