Review on the Development of Solid State Transformer

2021
According to future renewable electric energy distribution and management (FREEDM) system, solid state transformers play an important role in smart grid technologies. They have several advantages over conventional transformers such as bi-directional power flow, light in weight, compact size, etc.

A novel topology of solid state transformer

2010 1st Power Electronic & Drive Systems & Technologies Conference (PEDSTC), 2010
This 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.

Solid-State Transformations in Weldments

1993
Abstract 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 of aceclofenac: characterization, transformation

Journal of Pharmaceutical Investigation, 2012
The objective of this work was to investigate the existence of polymorphs and pseudopolymorphs of aceclofenac which is a peripherally acting, non-steroidal anti-inflammatory analgesic with anti-inflammatory, antiarthritic and antipyretic activities.

A solid-state relay for transformer switching

International Journal of Electronics, 1986
A 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 Phase Transformations

2004
The 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.

Solid-state transformer topology selection

2009 IEEE International Conference on Industrial Technology, 2009
This 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 and Reactions

2012
In 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.
