一种用于大功率中压三电平逆变器的改进型多模式同步空间矢量调制策略

The switching frequency of high-power medium-voltage three-level inverters is relatively low due to the limitation of switching loss. Thus, the output performance of the inverter will be deteriorated if the fundamental frequency is increased (in other words, the pulse number is decreased). To solve the aforementioned issue, synchronized modulation strategies are necessary to be adopted to ensure t...
