A solid state transformer

1980 IEEE Power Electronics Specialists Conference, 1980
This paper describes a solid state step up/down transformer system which also provides AC output voltage regulation. It uses PWM AC power switching to achieve high efficiences and uses no large inductive components. Its performance has been verified by extensive computer simulation of the entire system and breadboard testing of several of the key ...

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,

Virtual Transformer Operation of Solid State Transformer (SST)

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
This paper proposes a virtual transformer operation of a three-stage solid state transformer (SST) used in the distribution network. By tracking the AC voltage at medium voltage AC (MVAC) input side as the reference of low voltage AC (LVAC) output stage, voltage relationship between AC buses can be established, and the mutual voltage support can be ...

Solid-state transformations involving quasicrystals

Materials Science and Engineering: B, 1995
Solid-state transformations involving quasicrystals were studied in several aluminium-base ternary alloys. An ordering transformation of the icosahedral phase at room temperature was noticed. A transformation from higher symmetry of quasicrystals results in several orientational variants of the product phase, the total symmetry of which is the same as ...

Kinetics of polymorphic solid-state transformations

Journal of the Chemical Society, Faraday Transactions 2, 1984
Solid-state polymorphic transformations can have a profound influence on the processing and storage of some crystalline powders. Using classical models of nucleation and growth a framework is developed which highlights the importance of crystal size on the transformation rate.

Solid-State Transformations

2016
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.
