Abstract
The high-temperature operation of a silicon carbide gate turn-off thyristor is evaluated for use in inductively loaded switching circuits. Compared to purely resistive load elements, inductive loads subject the switching device to higher internal power dissipation. The ability of silicon carbide components to operate at elevated temperatures and high power dissipations are important factors for their use in future power conversion/control systems. In this work, a maximum current density of 540 A/cm/sup 2/ at 600 V was switched at a frequency of 2 kHz and at several case temperatures up to 150/spl deg/C. The turn-off and turn-on characteristics of the thyristor are discussed.
