Middle Frequency Transformer Investigation for Solid-State Transformer
2018 International Conference on Smart Grid (icSmartGrid), 2018This paper investigates the middle frequency transformer for the solid-state transformer. It is expected to be used in the traffic and power system. One of the key technologies is the solid-state transformer. The 3kHz, 5kVA transformers with some different core materials are manufactured.

Solid-state transformer topology selection
2009 IEEE International Conference on Industrial Technology, 2009This paper considers the design criteria of the solid-state transformer circuit, with special focus on the high voltage side. Three plausible multilevel converter configurations are identified and compared in terms of cost and voltage balance requirements.

Solid State Phase Transformations
2004The crystal structure of a metal is not necessarily stable at all temperatures below the melting temperature. This is due to the fact that the solid always assumes the crystal structure with the lowest Gibbs free energy, even if there are other crystal structures with a slightly higher free energy.

A solid-state relay for transformer switching
International Journal of Electronics, 1986A static relay, which can distinguish the magnetizing inrush current from the short-circuit current of a transformer is suggested. This eliminates the use of the desensitizing arrangement or the costly harmonic-current-restraint relay but preserves the inherent features of an over-current relay and the advantages of a static relay.

Crystal to crystal transformation in the solid state
CrystEngComm, 2004Either co-milling or simple mixing of benzoquinone (BQ) and diol crystals of varied melting point temperature produces adduct crystals through very slow and gradual molecular diffusion processes in the solid state. Their formation process was compared and discussed based on the crystal structures of the starting diols and the diol–BQ adducts.

Solid-State Transformations in Weldments
1993Abstract Solid-state transformations occurring in a weld are highly nonequilibrium in nature and differ distinctly from those experienced during casting, thermomechanical processing, and heat treatment. This article focuses on welding metallurgy of fusion welding of steels and highlights the fundamental principles that form the basis of ...

Solid-State Phase Transformations and Reactions
2012In Chapters 14 and 15, we discussed grain boundaries (GBs) and phase boundaries (PBs), respectively. Those two chapters described the interfaces and crystal defects. In Chapter 24, we then examined how the movement of GBs can lead to sintering, grain growth, and densification.

A solid-state transformation in 1,5-dichloroanthraquinone
Journal of Applied Crystallography, 19791,5-Dichloroanthraquinone undergoes a solid-state transformation at 470 K. The two modifications are very similar, except that a is greater than b above the transition temperature and the inverse is true at room temperature.
