Efficient, Reliable and Fault-Diagnosable Authentication Scheme for Smart Grids

Authentication is a crucial requirement for smart grid communications. However, the current authentication approaches in the smart grid relying on per-packet signature and per-signature verification schemes introduce heavy costs for computation and communication. Furthermore, despite being much desired by the electric power industry, there are still no efficient fault diagnosis tools to support...

Cree Silicon Carbide Power White Paper: Highly Efficient, and Compact ZVS Resonant Full Bridge Converter Using 1200V SiC MOSFETs

Rev. Abstract The most recent version (C2MTM) of Silicon Carbide (SiC) devices is used in a Zero Voltage Switching (ZVS) converter application. A 1200V, 160mohm SiC MOSFET from Cree Inc. is used to design a high-frequency ZVS LLC resonant fullbridge (FB) DC/DC converter. With the outstanding advantages of SiC MOSFET, which has lower junction capacitance and low-on-state resistor compared to a s...

Pushing Power Density Limits using SiC-JFet-based Matrix Converter

The omnipresent trend of increasing the power density of inverter technology lead to new developments in semiconductor material. As most of the benefits come from higher operating junction temperatures, it is mandatory to restrict the inverter design to peripheral components capable to work in these high temperature conditions. Eliminating the needs for large DC-link capacitors, the matrix conv...

Designing Of A Smart Transformer

As an integral part of the Smart Grid, smart transformers both work independently to constantly regulate voltage and maintain contact with the smart grid in order to allow remote administration if needed and to provide information and feedback about the power supply and the transformers themselves. Through a process known as voltage optimization, a smart transformer provides the exact amount of...
