Digital Control of High Temperature SiC Power Modules Utilizing HTSOI

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.
