Fault Characterization Through FPGA Undervolting [PDF]

, 2018
The power and energy efficiency of Field Programmable Gate Arrays (FPGAs) are estimated to be up to 20X less than Application Specific Integrated Circuits (ASICs). What is needed to close this gap is aggressive power/energy savings techniques.

Fault Detection in Power Distribution Networks Based on Comprehensive-YOLOv5

Sensors, 2023
Real-time fault detection in power distribution networks has become a popular issue in current power systems. However, the low power and computational capabilities of edge devices often fail to meet the requirements of real-time detection. To overcome these challenges, this paper proposes a lightweight algorithm, named Comprehensive-YOLOv5, for ...
