This site displays a prototype of a “Web 2.0” version of the daily Federal Register. It is not an official legal edition of the Federal Register, and does not replace the official print version or the official electronic version on GPO’s govinfo.gov.
The documents posted on this site are XML renditions of published Federal Register documents. Each document posted on the site includes a link to the corresponding official PDF file on govinfo.gov. This prototype edition of the daily Federal Register on FederalRegister.gov will remain an unofficial informational resource until the Administrative Committee of the Federal Register (ACFR) issues a regulation granting it official legal status. For complete information about, and access to, our official publications and services, go to About the Federal Register on NARA's archives.gov.
The OFR/GPO partnership is committed to presenting accurate and reliable regulatory information on FederalRegister.gov with the objective of establishing the XML-based Federal Register as an ACFR-sanctioned publication in the future. While every effort has been made to ensure that the material on FederalRegister.gov is accurately displayed, consistent with the official SGML-based PDF version on govinfo.gov, those relying on it for legal research should verify their results against an official edition of the Federal Register. Until the ACFR grants it official status, the XML rendition of the daily Federal Register on FederalRegister.gov does not provide legal notice to the public or judicial notice to the courts.

Title: Power Switching Semiconductor Devices Including Rectifying Junction-Shunts.
Abstract: Typical applications for switching power devices (e.g., IGBT or Power MOSFET) require reverse conduction for rectification or clamping by either an internal or external diode. Because Power MOSFETs have an inherent PiN diode within the structure, this internal diode must either be made to work effetely for the rectification and clamping, or must be bypassed by an external diode. Because the inherent internal PiN diode results in majority Start Printed Page 11619carrier injection from the drain-body junction (PN junction at Body-to-Drift-Layer interface) it has slow reverse recovery time and may result in SiC crystal degradation. The concept of inclusion of reverse conducting SIR junction shunts provides substantial benefits by: (1) Bypassing current flow from the inherent internal drain-body junction preventing it from injecting majority carriers and thus preventing slow reverse recovery and crystal degradation, and (2) enabling current to flow for voltages lower than the drain-body junction built in potential (e.g., approximately 3 V for SiC) and thus provides lower on-state losses than a PiN diode for the lower current range condition.Start Signature
