Streamlining Connected Object Energy Consumption.Streaming a HD movie requires more electricity than its takes to produce and transport a DVD of the same film. How can connected objects improve this situation?
Extending its expertise in high-brightness microdisplay technology for augmented-reality and other applications, Leti will demonstrate the world’s first wide video graphic array (WVGA) GaN microdisplay with 10-micron pixel pitch during Display Week in Los Angeles, May 21-26.
Leti and Liten, both CEA Tech institutes, developed the electronics and algorithms required to measure the internal temperature of a battery cell by estimating electrical impedance. The purpose of the solution is to detect the early signs of thermal runaway in embedded lithium-ion batteries.
The aeronautics and automotive industries are looking for more compact, efficient power converters.
A GaN power switch driver was recently integrated into a demonstrator system for a high-temperature application. This research will create new possibilities for the automotive, aeronautics, and mining exploration (drilling) industries.
Scientists at Leti, a CEA Tech institute, have made a major leap forward in energy conversion electronics with a new GaN transistor capable of handling up to 650 volts.
