摘要

This paper describes the manufacturing procedure, testing and application of a high temperature (HT) and radiation tolerant silicon carbide (SiC) semiconductor device technology used to fabricate a stepper motor driver circuit for HT spacecraft applications. The proposed circuit employs 4H-SiC MOSFET technology and diodes designed to operate at high ambient temperatures (>400°C). The discrete F...
