Navitas unveils 5th-generation SiC MOSFET platform with 35% improved switching figure of merit
Navitas Semiconductor has launched its 5th-generation GeneSiC technology platform, a 1200 V SiC MOSFET line based on what the company calls Trench-Assisted Planar (TAP) architecture. The design combines the ruggedness of a planar gate structure with the performance benefits of a trench in the source region. The headline improvement is a 35% better RDS(on) x… Read more »
UT Austin spinout Supra aims to recover gallium, scandium and other critical minerals from waste streams
Supra Elemental Recovery, a spinout from the University of Texas at Austin, has launched with a $2 million pre-seed round to develop technology for recovering critical minerals—including gallium and scandium—from domestic waste streams such as industrial byproducts, mine tailings and electronic waste. The US is currently 100% import-dependent for both gallium and scandium, elements essential… Read more »
Infineon launches isolated gate driver ICs with opto-emulator input for SiC migration
As the power electronics industry shifts from silicon IGBTs to SiC MOSFETs—driven largely by the efficiency demands of EV inverters, onboard chargers and DC fast charging—one persistent headache has been the gate driver. Legacy designs built around optocouplers and opto-emulators typically need significant rework to handle SiC’s faster switching speeds and higher noise immunity requirements…. Read more »
Vishay releases 1,200 V SiC MOSFET power modules for EV chargers in SOT-227 package
Vishay Intertechnology has introduced five 1,200 V silicon carbide (SiC) MOSFET power modules in the industry-standard SOT-227 package: VS-SF50LA120, VS-SF50SA120, VS-SF100SA120, VS-SF150SA120 and VS-SF200SA120. Vishay says the modules target medium- to high-frequency power conversion, where switching losses and thermal headroom limit efficiency, including EV offboard, switched-mode power supplies (SMPS), DC-to-DC converters, uninterruptible power supplies (UPS),… Read more »
Off-highway’s electric shift: why voltage, modularity and e-hydraulics matter
Electrification of off-highway vehicles isn’t new. What’s new is the combination of battery economics, tighter urban rules and a rapidly evolving global supply chain—forces that are pushing OEMs to rethink machine architecture, service strategy and the realities of charging on a jobsite. Danfoss Editron’s Eric Azeroual on off-highway electrification trends Electrification is often framed as… Read more »
Intrepid, Aquatech and Adionics complete test work at battery-grade lithium carbonate project in Utah
US potash producer Intrepid, water and process technology provider Aquatech and French lithium extraction firm Adionics have completed test work to produce battery-grade lithium carbonate from by-product brine at Intrepid’s Wendover, Utah potash facility. The test results demonstrate the ability to convert Intrepid’s Wendover brine and achieve a lithium extraction rate of 92.9% to produce… Read more »
Urban Foresight leads study into floating charging hubs for electric boats
A consortium led by UK sustainability consultancy Urban Foresight has won funding from Innovate UK to lead a study called CoastalCoRRE, which will explore the concept of modular, floating electric boat charging hubs. The idea is that the portable charging hubs could help overcome the physical, electrical and environmental constraints of remote coastal locations, where… Read more »
Allegro MicroSystems expands gate driver portfolio to simplify 800 V SiC power design
Allegro MicroSystems has released its AHV85003 and AHV85043 isolated gate driver chipset, expanding its Power-Thru isolated gate driver portfolio. This chipset joins Allegro’s existing AHV85311 integrated solution, forming a product ecosystem for high-voltage silicon carbide (SiC) designs in EVs, data centers and other systems. Allegro says that this new offering addresses the challenge of power… Read more »
Research from ANL and UChicago PME looks to resolve battery degradation by mitigating nanoscopic strains
New research from Argonne National Laboratory and the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) claims to have solved a battery mystery that has led to capacity degradation, shortened lifespan and, in some cases, fire. In a paper published in Nature Nanotechnology, researchers uncovered some of the root causes and ways to… Read more »
