Abstract Eutectoid and peritectoid transformations are classified as solid-state invariant transformations. This article focuses primarily on the structures from eutectoid transformations with emphasis on the classic iron-carbon system of steel. It reviews peritectoid phase equilibria that are very common in several binary systems.

Soft-switching solid state transformer (S4T)
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016This 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,

Auxiliary power supply for solid state transformers
2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2016This paper discusses different ways to obtain an auxiliary power supply (APS) to a solid state transformer (SST) that utilizes the modular AC-DC-DC-AC configuration. A local distributed source, that consists of two APS per module, one for medium voltage (MV) side and another one for low voltage (LV) side is proposed.

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.

A novel topology of solid state transformer
2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC), 2010This paper introduces a new topology for implementing a solid state transformer. The advantages of the proposed topology include a reduced number of SiC MOSFETs, lower cost and smaller switching losses. Simulation results are given to demonstrate the performance of the proposed topology.

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.

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 ...
