LCL滤波电压源逆变器的图形化阻抗重塑方法

Impedance reshaping has proven to be effective to ensure the stability of the LCL-filtered voltage source inverters against the grid impedance variation. Lots of reshaping approaches have been developed to date. However, there lacks an intuitive approach for the engineers to quickly determine a proper one from various reshaping approaches. This letter proposes a graphical impedance reshaping appro...
