Status of the DARPA WBST High Power Electronics Program in SiC Device Development and Technology Transition



Allen R. Hefner Jr., Sharon Beermann-Curtin


The emergence of High-Voltage, High-Frequency (HV-HF) Silicon-Carbide (SiC) power devices is expected to revolutionize industriall and military power generation, transmission and distribution systems. The DARPA Wide Bandgap Semiconductor Technology (WBST) High Power Electronics (HPE) program is spearheading the development of this HV-HF SiC power semiconductor technology. This paper describes recent progress of the WBST HPE program in devices development and in circuit performance demonstrations of the devices. The paper also discusses the planned program to demonstrate a prototype 2.7 MVA Solid State Power Substation (SSPS) using the HV-HF SiC power device technology, and introduces the planned projects to establish reliability and manufacturability of the materials, devices, and packages for the HV-HF SiC power devices.
