关于“用于中点电压反馈的三电平中点钳位变换器改进虚拟空间矢量调制”的评论

In the paper by Xiang et al. (IEEE Trans. Power Electron., vol. 33, no. 6, pp. 5452–5464, Jun. 2018), the authors proposed an improved virtual space vector modulation for three-level neutral-point-clamped converter. However, some problems are worth being discussed about vector synthesis of the improved virtual space vector modulation. This paper presents some comments and results concerning the ab...
