基于无源性增强的LCL型并网逆变器电容电流有源阻尼通用设计方法

Grid-side current control based on capacitor-current-feedback (CCF) active damping is a common control method for LCL-type grid-tied inverters. The control system should not only ensure inverter stability under complex grid conditions, but also be simple in structure. Therefore, the multiobjective design for the CCF control is proposed to enhance the passivity, while improving the internal stabili...
