The race to build lighter, more powerful electric motors has just produced a startling new benchmark: an in-wheel drive unit that delivers 1,000 hp per corner in a package small enough to disappear ...

Modern battery-powered motor products are increasingly being designed using three-phase brushless DC (BLDC) and permanent-magnet synchronous motors (PMSM) due to their improved efficiency, compact ...

We’ve long-admired internal combustion engines for their power density pursuits. Extremely high horsepower-to-liter ratios for naturally aspirated cars like the Honda S2000, Ferrari 458 Speciale, or, ...

The resistivity versus temperature curves of pure Cu, CuCr alloys and CuCr/Gr wires were tested to determine the effect of Cr and graphene incorporation on resistivity. The study, led by Tingting Zuo, ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

What all-electric aircraft and GaN FETs have in common. The differences between LLC+Buck and Boost+LLC-DCX circuits. We’ll kick off this article with a power component recently introduced by Efficient ...

Texas Instruments Inc. (TI) has launched two power-conversion device portfolios that deliver higher power density in smaller spaces. These new power devices include the 100-V integrated gallium ...
