Take advantage of current control topologies without self-heating error while retaining the 317/337's fault protection ...

This paper presents a two-stage current limiting control strategy with fault ride-through capability for direct-droop-controlled grid-forming (GFM) inverters. The proposed two-stage approach comprises ...

To avoid excessive start-up inrush current and hardware overdesign, the fixed-frequency variable duty-cycle soft start-up strategy is often adopted. However, in this conventional strategy, the optimal ...
