Performance of a 1-MVA HTS demonstration transformer

IEEE Transactions on Appiled Superconductivity, 1999
We report on test results for a single phase, 60-Hz, 13.8 kV/6.9 kV, 1-MVA high temperature superconducting (HTS) transformer which was completed in February, 1998. This transformer models in many ways a full scale section of a 30-MVA HTS commercial transformer design. The transformer windings are cryocooled in the range of 25 K and are made with a low-

Electromagnetic Analysis of an Air-Core HTS Transformer

IEEE Transactions on Applied Superconductivity, 2019
Since there is no iron core and the energy is only coupled through the primary and secondary windings, air-core transformers have advantages of no iron loss, no magnetic saturation, and compact in size, which make them attractive to be studied for practical applications. Due to its high current density and low loss, high temperature superconductor (HTS)

Tests and Performance Analysis of 2G HTS Transformer

IEEE Transactions on Applied Superconductivity, 2013
Transformers represent one of the oldest and most mature elements in a power transmission and distribution network. The new superconducting transformers are smaller and lighter than conventional ones and they have lower power losses. Also, the new 2G superconducting tapes with high resistivity in the normal state allow to build transformers with high ...

Hilbert-Transformation (HT)

1985
In Aufgabe A7.1 wird die HT im Zeitbereich angewendet, auserdem wird der „Hilbert-Transformator“ eingefuhrt, dessen Impuls- und Sprungantwort in weiteren Aufgaben dieses Kapitels Anwendung findet. Die HT im Frequenzbereich verbindet Real- und Imaginarteil der Ubertragungsfunktion eines realisierbaren Systems. Dies wird in 7.2 naher untersucht.

Development of HTS Transformer-Rectifier Flux Pumps

2020
High Temperature Superconductor (HTS) magnets are enabling components for many valuable applications including medical imaging and fundamental physics research. One major inconvenience of using superconducting components is the need to cool them to a very low temperature, and once at this low temperature, to power them.
