Modelling of magnetostrictive vibration and acoustics in converter transformer
IET Electric Power Applications, 2021 The converter transformers are susceptible to more noise and vibration when compared to power transformers due to the presence of DC bias in the DC transmission line. DC bias occurs mostly due to inaccuracies in valve firing resulting in a small residual

Planar transformer isolated DC-DC Converter for Solid-State Transformer
, 2020 The demand for high frequency, high power density and high efficiency on power converters has been increasing through the years. Solid state transformer (SST), which is typically formed by three stages, one being DC/AC inverter, which is controllable, one being medium-frequency transformer isolated converter and the other being AC/DC rectifier, has ...

DC-DC transformer multiphase converter with transformer coupling for two-stage architecture
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010 This paper presents an analysis of a very high efficiency topology based on a multiphase converter where the coupling among the phases is done by means of transformers. Since energy is not stored in the transformers, it is transferred directly from the input to the output. This topology along with its control strategy, were previously reported in state
