摘要: 为了改善电压不平衡时矩阵变换器的输入、输出性能,文章提出了一种改进的双电压合成策略,介绍了一种新的指令电流计算公式,即通过三相输入电压直接计算正、负序电压以产生指令电流。仿真实验验证了不平衡条件下双电压合成控制策略改进研究的正确性。Abstract: In order to improve input and output performance of matrix converter when voltage is not balanced, the paper proposed an improved strategy of double-voltage composition,introduced a new formula that used to calculate command current,namely through 3-phase input voltage directly calculated positive and negative voltage to get command current.The simulation experiment proved the validity of improved strategy of double-voltage composition under unbalanced input.
