Stability of LCL-filtered grid-connected inverters with capacitor current feedback active damping considering controller time delays
Abstract This paper investigates the stability of LCL-filtered grid-connected inverters with capacitor current feedback (CCF) active damping. The impact of time delays in the digital controller on active damping and its equivalent virtual impedance is analyzed. The inherent relationship between thes...
