At the end of Phase II of this program, a fully-functional 15 kW/300�C rated power converter IC equipped with AlGaN/GaN-on-Si MOS-HFETs, Natural SuperJunction (NSJ) SBRs as free-wheeling diodes and on-chip SiC or III-Nitride gate drive circuitry will be demonstrated at a switching frequency of ≥ 1 MHz and at a temperature of ≥ 300 �C. Another major objective during Phase II will be the construction of Rad-Hard packaging for the power ICs. Phase II will be focused on the design and integration of Si/GaN gate-drive circuitry with the power SBRs and transistors to create high-power integrated circuits. Phase I of this proposed work will focus on the optimization of the design and fabrication of the AlGaN/GaN-Si MOS-HFET and NSJ SBR devices. The proposed AlGaN/GaN-Si power converters to be developed in this program will usher in a new generation of high-efficiency, low-cost, and radiation-hard power conversion units on-board future NASA spacecraft. TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)Ĭapitalizing on a potent confluence of expertise in III-Nitride epitaxy, GaN-Si power device designs, and wide-bandgap power electronics, researchers at GeneSiC Semiconductor and Cornell University jointly propose a SBIR program focused on the development of 15 kW/300 �C-rated power converters using AlGaN/GaN-Si MOS-HFETs and Schottky rectifiers.
