Enabling Magnetics for Solid State Transformers DOE TRAC program
NC State will work on developing magnetics for solid state transformers for the National Energy Technology Laboratory's soft magnetic material development. The team will focus on testing the magnetic components under square wave excitation using Low Voltage and Medium Voltage Core Loss Test Systems with 1.2kV and 10kV SiC MOSFETs. Core selection will be based on materials applicable to power electronics-based converters and motors with an emphasis on their potential for high-frequency and high-power applications. Experimental results will be organized into data sheets and leveraged by TRAC program participants and published as advanced data sheets. The team will also characterize cores developed under Task 3.0 and advance the existing systems for other excitation waveforms, including sinusoidal waves.

More Details
NCSU will be working on Enabling Magnetics for Solid State Transformers for National Energy Technology Laboratory’s soft magnetic material development. NCSU will leverage the Low Voltage (LV) and Medium Voltage (MV) Core Loss Test Systems (CLTSs) with 1.2kV and 10kV SiC MOSFETs, respectively, built under the existing program to characterize selected magnetic cores and insulation materials under application relevant and practical wave excitations. The team will focus on testing the magnetic components under square wave excitation using the LV and MV test systems. The bases for core selection are core materials applicable to power electronics-based converters and motors with an emphasis on their potential for high-frequency and high-power applications. Experimental results will be organized in the form of data sheets and fitted based upon established models to be leveraged by TRAC program participants in their own efforts and published as advanced data sheets. The target will also be in characterizing the cores that are being developed under Task 3.0 under this project and advancing the existing systems for other excitation waveforms, including sinusoidal waves.
