This Startup Shows Why the U.S. CHIPS Act Is Needed

Electrical, Electronics & Instrumentation, Metallurgy & Material Science

There’s a certain sameness to spaces meant for tech startups: flexible cubicle arrangements, glass-encased executive offices, whiteboard walls awaiting equations and ideas, basement laboratories for the noisier and more dangerous parts of the process. In some ways the home of Ideal Semiconductor on the campus of Lehigh University, in Bethlehem,…

The New, New Transistor

Electrical, Electronics & Instrumentation, Mechanical, Production & Manufacturing

Over the past decade, one of the biggest stories in semiconductors has been a surprise eclipsing of traditional silicon—in the field of power electronics, where silicon carbide (SiC) and gallium nitride (GaN) have raced past silicon to capture multibilllion-dollar segments of the market. And as major applications fell to these…

Electrical, Electronics & Instrumentation

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over…
