Experimental study of the self-disturbance phenomena in a halfbridge configuration of Si IGBT and SiC MOSFET switches
This paper investigates the gate-driver design challenges encountered due to the fast switching of wide band-gap semiconductors (here, SiC MOSFETs) in the half-bridge configuration.
Conducted EMI reduction in a 100kW 1.2kV Dual Active Bridge converter
The experimental studies show the effects of the transformer construction and vector group (star/delta) on the common-mode currents through the gate drivers of SiC MOSFETs in a 100kW 1.2kV three-phase dual active bridge converter.
