Digital Control of High-Temperature SiC Power Modules Utilizing HTSOI

摘要

This paper describes a SiC-based stackable DC/DC converter system capable of operating at high temperature. The system is capable of fault tolerance and complex power management. These functions require complex control; however, high-temperature operation typically precludes the use of conventional control circuitries. Therefore, the present work seeks to develop an advanced digital controller capable of high-temperature operation. This is accomplished by utilizing the currently available suite of High-Temperature-Silicon-on-Insulator (HTSOI) technologies.
