Detecting early-stage failure in electric power conversion devices

Researchers used acoustic emission during power cycling tests to monitor in real time the complete failure process--from the earliest stages -- in silicon carbide Schottsky diodes. This development will help solve wear-out failure problems that are limiting advanced applications in computers, solar cells, and many other devices.
