A Capacitor-Current-Feedback Active Damping Control Strategy

Abstract: Capacitor-current-feedback (CCF) active damping is widely used to deal with the hazard of LCL filter resonance in the grid-connected inverter based on either phase lead or lag compensation, and the effect of active damping on open-loop of the control system can be evaluated directly by its equivalent impedance.
