Phase Reshaping via All-Pass Filters for Robust LCL-Filter Active Damping
IEEE Transactions on Power Electronics, 2020 Active damping is a common way to stabilize the current control of LCL-filtered converters. In this paper, the stable region of −180º-phase-crossing is firstly identified within a predefined range of grid impedance and LCL parameter variations. Once the phase of the current control loop is in the identified region, a stabilization control can be ...
