Abstract :
Design, operation, and performance evaluation of a 180 W, 100 kHz, 270 V/28 V two-transistor forward dc-dc power converter are reported for elevated temperatures up to 200°C. Use of SiC power semiconductor devices, and high temperature powdered ferrite (for magnetics design), and characterization of ceramic (X7R) capacitors´ leakage current over temperature are presented as well.
