一种用于四电平嵌套中点钳位逆变器的简化空间矢量调制方法，实现飞跨电容电压的完全控制

Four-level nested neutral-point clamped (NNPC) inverters experience severe voltage balancing problems under low output-frequency conditions when the conventional four-level space vector modulation (4L-SVM) technique is applied, which limits their wider application. In order to get a complete control of the flying-capacitor voltages, and to alleviate the calculation burden of conventional 4L-SVM, a...
