Current-Limiting Control for Fault Ride-Through of LLC-based Solid-State Transformer in Data Centers

Solid-State Transformers (SSTs) are increasingly proposed as the interface between distribution grids and data centers due to flexible power flows and fast dynamic response. However, when a short-circuit fault occurs in a load branch, the SST with a voltage-source-type DC-DC stage is forced to shut down due to fault cu...
