摘　　要：以简化计算为目的,提出了一种基于参考信号的矩阵变换器空间矢量简化调制算法,它通过参考信号的简单数学运算来实现扇区判断和占空比计算,省略了传统方法中复杂的坐标变换和反三角函数运算。同时,从运行安全性角度出发,提出一种改进的混合型换流方法,确保换流过程的安全执行。最后,仿真结果验证了上述方法的正确性和可行性。In order to simplify computation,a simplified space vector modulation algorithm based on referencesignals for matrix converter was proposed. In the algorithm,the sector judgment and duty cycle computation wereimplemented through simple mathematical operation of reference signal,with the advantages of cutting down thecomplex coordinate’s transformation and inverse trigonometric computation which are reguired in the conventionalmethod. While,aimed to keep safety,an improved hybrid commutation strategy was also proposed,which avoided thefailure in commutation. In the last,the simulation and experiment results validate the effectiveness and feasibility ofthose proposed methods.
