Novel Active Damping Design Based on a Biquad Filter for an LLCL Grid-Tied Inverter
LLCL filters for grid-tied inverters have been adopted to get better performance for the harmonics near the switching frequency than commonly used LCL filters. However, the resonant peak caused by a pair of unstable resonance poles of the LLCL filters is introduced and makes the system become unstab...
