等频条件下模块化多电平矩阵变换器八分量控制中的低频环流注入

The modular multilevel matrix converter ($\mathrm{{\mathbf{M}}}^{3}$C) is a topology suitable for ac–ac fields, such as wind power conversion systems, large-capacity electric drives, etc. However, when the input frequency of the system is close to or equal to the output frequency, large voltage fluctuations even unbalancing will produce on the dc capacitors of the submodules, which limits the appl...
