Power usage effectiveness, or PUE, is the go-to sustainability metric for data centers. But it says nothing about the power loss between the POL converter and the AI processor itself.
Amprius announced fourth-quarter production of a 500-Wh/kg battery cell aimed at stratosphere-based communications UAS, which may render SpaceX's LEO satellites obsolete.
As data centers become larger, denser, and more power-hungry, engineers are forced to rethink how they manage safety and maintenance — and how both factor into uptime.
STMicroelectronics’ new GaN-based power semiconductors are designed to improve efficiency and increase power density in applications such as AI, robotics, industrial power supplies, and smart-grid converters.
Research from Tokyo University of Science shows how rheo-impedance spectroscopy links slurry shear conditions during coating to battery performance, enabling data-driven optimization and improved manufacturing efficiency.
Alpha and Omega’s new digital multiphase controllers and smart power stages deliver industry-leading low quiescent power, extending mobile battery life by up to an hour.
Infinitum’s advanced motor system improves power quality by reducing harmonics at the source, helping customers unlock additional electrical capacity while lowering energy use.
A research team from MIT demonstrated a low-temperature process that could unlock cleaner lithium from America’s abundant hard rock while minimizing waste.
Enphase’s new SST architecture, which aligns with NVIDIA’s 800-V DC roadmap, uses a meshed array of sub-1-kV bidirectional GaN switches to provide scalability and distributed redundancy.
