Abstract :
The next generation of power electronics will use high temperature silicon carbide semiconductors. To utilize the capabilities of these devices, high temperature magnetics and other passive components are required. A 300 C ferrite material has been developed to operate at over 300 degree C combined ambient and rise. A 1.5 kV, 270 Vdc to 28 Vdc forward converter transformer has been built with this material and has been tested for 600 hours at >290 C ambient. Both test data and analysis are presented to show the material capability and techniques for high temperature windings. The test data and analysis includes a discussion of various winding and high temperature insulation techniques consistent with high voltage and power electronics high frequency magnetics issues.
