Overloading Scenario in Solid State Transformer [PDF]

open access: yes2020 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 ...
