一种用于中压SiC半桥驱动的高隔离门极驱动电源

For medium-voltage wide bandgap devices, the interdependence between isolation capability and coupling capacitance is the major barrier to compact and insulation-reliable gate driver power supplies (GDPS). This article proposes a loosely coupled transformer with a customized T-shaped core and printed circuit board (PCB) coils, achieving high isolation and low capacitance within a limited footprint...
