I. General InformationII. System CompositionIII. System Function and StandardGenerally, partialdischarge occurs at a position where the properties of the dielectric materialare not uniform. At these locations, the local electric field strength isenhanced, and local electric field strength is too large, resulting in localbreakdown. This partial breakdown is not the total breakdown of the insulatingstructure. Partial discharges typically require a certain amount of gas spaceto develop, such as gas voids inside the insulation, adjacent conductors, orinsulating interfaces.

The present paper reports on the first study of in Si or GaAs devices with the same blocking voltage [1– the critical charge density in high voltage SiC thyristors 3]. Silicon carbide devices show faster switching [4–6] with breakover voltage of 2.6 kV. and lower residual voltage drop at very high current densities in comparison with the identically rated Si and GaAs structures [7,8].
