Soft-switching solid state transformer (S4T)

2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016
This paper presents a new topology for a fully bidirectional soft-switching solid state transformer (S4T). The minimal topology, featuring 12 main devices and a high-frequency transformer, does not use an intermediate DC voltage link, and provides sinusoidal input and output voltages. The S4T can be configured to interface with two-or multi-terminal DC,

High-Frequency Partial Discharge Characteristics of Solid-State Transformer Interturn Multilayer Insulation Under Repetitive Electrical Stress

IEEE transactions on industrial electronics (1982. Print)
The solid-state transformer (SST) was regarded as the ideal power router in the energy Internet. However, the partial discharge (PD) in tightly packed SST is one of the main causes of interturn multilayer insulation premature failure.

Transition state analysis of solid-solid transformations in nanocrystals

The Journal of Chemical Physics, 2009
A systematic simulation methodology is introduced for the accurate determination of experimentally measurable quantities characterizing solid-solid phase transformations under pressure. The atomistic mechanisms of nucleation and growth in a structural transformation of pressurized CdSe nanocrystals are identified using transition path sampling computer
