This paper presents embedded magnetic transformers to address MV Utility. Both control and power transformers are designed to exhibit low inter-winding capacitance, while maintaining the clearance and creepage distance that meet IEC standards. In this digest, the transformer device characteristics are presented. The results of AC isolation tests are also presented to validate the integrity of the insulating material. The proposed gate drive transformers are aimed at providing a reliable and cost efficient means for implementing power systems using MV SiC MOSFETs.
