Recent advancements in wide-band gap switching devices have led to the
emergence of numerous medium voltage power electronic applications, including
solid-state transformers (SSTs). The medium frequency transformer
(MFT) is a crucial component of every SST, but faces significant
design challenges due to the requirements linked to the high operating
frequency. The prevention of partial discharges (PDs) in the insulation
material is of high importance as they can significantly reduce the MFT’s
insulation lifetime.To address this challenge, HPE is currently investigating
and comparing discharge inception models.
In this thesis you will contribute to this project, by investigating, comparing
and testing different PD measurement techniques to help deriving design
rules for the construction of MFTs. The results of your thesis will be of
great interest and will contribute to the development of more compact and
reliable MFT designs.
