ON Semiconductor announces rugged automotive SiC Diodes

ON Semiconductor has introduced a robust line of automotive-grade silicon carbide (SiC) Schottky diodes. The AEC-Q101 diodes can handle high surge currents and are meant to operate from -55° to 175° C. There are several reasons why SiC diodes are ideal for automotive applications. They are smaller and cheaper compared to alternatives, have higher power densities, and create… Read more »

Wolfspeed Technology introduces third-gen 1,200 V SiC MOSFET

Only one year after they were first introduced, Cree’s Wolfspeed Technologies has announced its third generation of 1,200 V SiC MOSFETs. Designed for EV powertrain applications, Wolfspeed claims that the MOSFET has the highest figure of merit on the market today, with low drain-source on resistance (RDS) performance and the industry’s lowest switching losses. Samples are currently available… Read more »

Webasto to acquire AeroVironment’s Efficient Energy Systems for $35 million

Automotive supplier Webasto is set to acquire AeroVironment’s Efficient Energy Systems (EES) branch, pending several more heaps of paperwork. The $35-million acquisition includes EES’s charging and docking technologies, further diversifying Webasto’s portfolio.  Webasto originally specialized in heating, cooling and sunroof design for automotive applications, but it has been steadily working to expand into the EV energy… Read more »

Volkswagen developing quantum computing for battery simulation at molecular level

Volkswagen has successfully simulated several molecules commonly found in batteries using quantum computing. The simulations currently include simple chemicals such as lithium-hydrogen and carbon chains, but will eventually include more complex compounds. The end goal is a simulation of an entire battery without the use of a physical model. Volkswagen will share its work at the upcoming… Read more »

TDK introduces magnetic sensor with 3D and angular output capabilities

Magnetic sensors have several automotive applications, including determining the positions of clutch pedals, engine strokes, and valves. However, their use has been limited to linear position measurements. The current standard, Hall sensors, can only detect changes in the magnetic field perpendicular to its chip. TDK Corporation has introduced the new HAR 379x sensor, which uses its… Read more »

New solid polymer electrolyte doubles proton flow rate

Engineers from the University of Pennsylvania and the University of Florida have recently made a breakthrough in the development of solid polymer electrolytes (SPEs). Current liquid electrolytes require thick, heavy housings in order to prevent leaks and fires from punctures, increasing their bulk and weight. SPEs solve many of these problems, but until recently, they were… Read more »
