摘要
This study presents a fast reactive current detection (RCD) method based on closed-loop resonant filter for single-phase grid-connected inverters. The developed closed-loop resonant filter-based RCD (CLRF-RCD) technique with shorter time delay can enhance the dynamic performance of reactive current detection, which is beneficial for achieving faster reactive current compensation and/or reactive power regulation in single-phase grid-connected power systems. The optimal design of CLRF-RCD is presented in detail, together with the comparison of CLRF-RCD with the conventional second-order generalised integrator-based RCD. Finally, the simulation and experimental results validate the feasibility of the developed CLRF-RCD algorithm.
