| 摘 要： | 提出了一种SVPWM(空间矢量脉宽调制)新控制策略,选取与参考矢量距离最近的电压矢量作为最优矢量传送给负载.由于级联型多电平变频器电压矢量空间分布的稠密性,在调制深度足够大的情况下,其误差完全可以被忽略.通过MATLAB/Simulink仿真,得到了验证.该方法非常易于数字化实现,能满足实时控制的需要.

| Abstract: | It is presented a novel SVPWM control strategy for cascaded multilevel inverters.The closest space voltage vector to the reference vector should be chosen as the optimal one to be transmitted to load.When modulation is enough, the error can be neglected for the distribution density of cascaded multi-level converter's space voltage vectors. The algorithm is proved by MATLAB/Simulink simulation. It can be realized easily and meets the need of real-time control. |
