In the solid state transformers with medium voltage SiC-Devices, it is possible to achieve very high efficiency, although designing a sufficiently high switching frequency in order reduce filter elements, volume and mass of the transformer.

As a focus of the paper “Characterization of a 300 kW isolated DC/DC converter using 3.3 kV SiC-MOSFETs”, which was awarded with the Best Paper Award at PCIM 2021, the solution of solid state transformers is restated to be very attractive, in particular, as their efficiency can be further improved depending on the characteristics of the devices.
