Active control of DC fault currents in DC solid-state transformers during ride-through operation of multi-terminal HVDC systems [PDF]
, 2016 When a pole-to-pole dc fault occurs in a multi-terminal HVDC system, it is desirable that the stations and dc solid-state transformers on healthy cables continue contributing to power transfer, rather than blocking.

Overloading Scenario in Solid State Transformer [PDF]
2020 11th International Renewable Energy Congress (IREC), 2020 Nowadays, solid state transformer (SST) is been considered as an alternative option in smart grid where additional ancillary services that cannot be provided by conventional line frequency transformer (LFT) are required. However, the power transmission capability of SST is limited to that of its semiconductor switches which are power electronics ...
