Medium-frequency transformer (MFT) is an essential device in the smart solid-state transformer (SST) prototype. Compared with the well-defined principle design of magnetic core and windings in MFT, ...

1.2kV-class 4H-SiC super junction (SJ) DMOSFET was designed and optimized in this work. Several P-pillar structures and dosage variation were used to target the charge balance condition in order to ...
