Solid-State Bipolar Marx Converter with Output Transformer and Energy Recovery [PDF]
, 2012 The purpose of this paper is to present and discuss a general HV topology of the solid-state Marx modulator, for unipolar or bipolar generation connected with a step-up transformer to increase the output voltage applied to a resistive load.

Finding transition states for crystalline solid–solid phase transformations [PDF]
Proceedings of the National Academy of Sciences, 2005 We present a method to identify transition states and minimum energy paths for martensitic solid–solid phase transformations, thereby allowing quantification of the activation energies of such transformations. Our approach is a generalization of a previous method for identifying transition states for chemical reactions, namely the climbing image-nudged

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 ...
