High frequency loss evaluation in high frequency multi-winding power transformers
Proceedings of 1995 IEEE Applied Power Electronics Conference and Exposition - APEC'95, 1995A high frequency power transformer (HFPT) with twin secondaries is generally analyzed with each primary ampere-turn being canceled by an equal contribution from each of the two secondaries. Such a methodology does not indicate worst case high frequency losses.

High-frequency power transformer modeling
2013The detailed study of high-frequency over- voltages propagating inside the electrical systems of a power plant requires a precise modeling of power transformers at high frequencies. These over- voltages may originate from lightning overvoltage propagating along the transmission line and crossing the step-up transformer, they may originate also for ...

Difficulties in high frequency transformer modelling
2015Traditional transformer models available in EMTPlike software packages are not capable of representing transformer behavior during a transient state, which includes high frequencies, since they usually do not adequately take into account the transformer resonant behavior caused by its highly complicated design.
