A novel active damping control based on grid-side current feedback for LCL-filter active power filter

Energy Reports, 2020
LCL filter is widely used in grid-connected converters for good harmonic mitigation performance. However, resonance poles of LCL filter challenge system stability, especially in a digital control system.
