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.
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.
In this paper, a methodology is proposed to define the optimal rated power and number of PEBBs.
A synergetic effect between hBN and alumina has been observed regarding thermal and electrical properties. A 500% increase in the thermal conductivity could be achieved with a limited impact on viscosity increase.
One of the possible SF6 alternatives that emerged in recent times is a fluoronitrile (FN), NovecTM 4710, based mixture.
This paper presents a methodology for the modelling of a 25 kV-50 Hz railway infrastructure, for frequencies from 0 to 5 kHz.
Using Gibbs free energy method, a theoretical study has been conducted on SF6 replacement candidates listed above.
This article presents the measurements of the equivalent B(H) and the equivalent magnetic permeability of two three-phase MFT prototypes.
This paper aims at the detection and characterization of partial discharges (PD) in GIS under HVDC constraints in the presence of a protrusion/metallic particle on the high voltage conductor.
Recent studies have demonstrated that fluoronitrile (FN) NovecTM 4710 and fluoroketone (FK) NovecTM 5110 show higher dielectric strength than SF6. These gases can be mixed with a buffer gas such as CO2 and technical air to have suitable dielectric properties for high voltage insulation applications.
