Integration of Novel High-Frequency Transformer with Silicon-Carbide Schottky Diodes [PDF]
This paper presents a novel and compact structure which integrates silicon-carbide (SiC) Schottky diodes within a high-frequency transformer (HFT). The proposed structure would reduce the volume of a power converter and in turn the system to which it is ...
