| 摘 要： | 针对多电平逆变器提出一种简化的电压空间矢量脉宽调制方法,该方法是先将电压矢量向复平面分解,并以相应的基准对分解后的横纵坐标进行标幺化,然后通过参考电压矢量来选择三个电压矢量和对应的作用时间,最后再将所选择的电压矢量变换为对应的三相电压波形.该方法具有实现简单、通用性强等优点,而且还具有较好的抑制多电平逆变器共模电压的作用.通过Matlab/Simulink仿真,证明了该方法的正确性和可行性.

| Abstract: | A simpler method of voltage space vector pulse width modulation based on mutli-level inverter is presented.Firstly,voltage space vectors are decomposed in complex plane.Moreover,decomposed abscissa and ordinate are normalized with per unit system transform.And then,three voltage vectors and their operation time are selected with reference voltage vectors.Finally,the selected voltage vectors are transformed into corresponding three phase voltage waveforms.This method has many strongpoints,such as realization... |
