Improved PR Control Strategy for an LCL Three-Phase Grid-Connected Inverter Based on Active Damping
Aiming at the problem of power coupling and complicated decoupling in the <i>d</i>-<i>q</i> coordinate system of a three-phase grid-connected inverter, a current closed-loop control strategy based on an improved QPIR (quasi-proportional integral resonant) controller in the &l...
