Abstract :
Summary form only given. In this paper, the switching performance of a SiC bipolar transistor was presented. The transistors had a static current gain of approximately 9 at room temperature. Switch frequencies up to 1 MHz and 300 V were tested with a resistive load of 1 kΩ, which the SiC BJT managed well. The breakdown voltage was around 400 V, which is 25% of the ideal breakdown voltage.
