Capacitor-Current-Feedback With Improved Delay Compensation for LCL-Type Grid-Connected Inverter to Achieve High Robustness in Weak Grid
To attenuate the resonance of the LCL filter, capacitor-current-feedback (CCF) active damping has been extensively adopted in LCL-Type grid-connected inverters. Owing to the appearance of a negative damping region caused by the digital control delay, however, the damping performance has significantl...
