A Solid State Transformer model for power flow calculations [PDF]

open access: yesInternational Journal of Electrical Power and Energy Systems, 2017
This paper presents the implementation of a Solid State Transformer (SST) model in OpenDSS. The goal is to develop a SST model that could be useful for assessing the impact that the replacement of the conventional iron-and-copper transformer with the SST

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 ...

Amorphous-to-Quasicrystalline Transformation in the Solid State

Physical Review Letters, 1985
${\mathrm{Al}}_{84}$${\mathrm{Mn}}_{16}$ multilayer films have been amorphized by room-temperature ion-beam irradiation. The amorphous phase was transformed into the quasicrystalline state through two routes: thermal and ion-beam-assisted thermal. The intensity of the quasicrystalline electron diffraction increases continuously with annealing between ...

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,

Auxiliary power supply for solid state transformers

2016 IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2016
This 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.

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.
