Abstract

This DOD STTR project is to design and demonstrate a SiC-based power converter system for electric torpedoes and underwater vehicles, addressing the related technical issues and quantifying the system benefits. The resultant SiC inverter will be capable of working at high power densities, high temperatures, and high frequencies, and thus achieving the advantages of high efficiency, small size, and light weight. In this Phase I, Aegis will carry out the technical feasibility study of the proposed SiC inverter, including: (1) Circuit design and modeling to evaluate the SiC inverter performance as comapred with a Si-based inverter , (2) High temperature packaging and thermal management to support the SiC converter work in the constrained environment, (3) Gate drive and contorl suitable for SiC power devices, and (4) Build and characterize the SiC inverter.
