Performance Analysis of 10 kV, 100 A SiC Half-Bridge Power Modules



Allen R. Hefner Jr.


Abstract: The DARPA Wide Bandgap Semiconductor Technology (WBGS) High Power Electronics (HPE) Phase II program is developing high-voltage, high-frequency SiC device and package technology needed to meet the specific program objectives for a 13.8 kV, 2.75 MVA Solid State Power Substation (SSPS) being developed by the DARPA WBGS-HPE Phase III program. In this paper, the performance of the HPE Phase II SiC device and package technology is eval((uated and a physics-based electro-thermal model is used to investigate the design trade-offs for 100 A, 10 kV SiC half-bridge power modules. This electro-thermal model is also used to demonstrate the expected performance of the half-bridge modules in a representative HPE Phase III SSPS topology.
