Characterization of SiC JFET in Novel Packaging for 1 MHz Operation

Article Preview

Abstract:

A high power discrete SiC-JFET package for accelerator applications has been developed and tested. Successful operation with a dc voltage of 1 kV, a drain current of 27 A, and a repetition rate of 1 MHz was confirmed. Thermal analysis was carefully attempted. The heat dissipation capacity of 235 W with a water-cooled heat sink and the thermal resistance from its junction to outer-surface of 0.56 K/W were demonstrated. These results exhibit the SiC-JFET is a promising device for a switching power supply in future digital accelerators.
