The power semiconductor evolution started with germanium and selenium devices that succumbed to silicon types around the 1950s. Broader silicon usage stemmed from its improved physical properties ...

Electromagnetic far field impedance is about 377Ω = 120π or 29,9792458 × 4 × πΩ for the vacuum velocity of light. Any electromagnetic wave far enough from its source (rule of thumb >wavelength/2 × π) ...

Power over Ethernet (PoE) is not rocket science, but it’s not plug-and-play magic either. This short primer walks through the basics with a few practical nudges for those curious to try it out. It’s a ...

Editor’s note: I hope to see many of my EDN and Planet Analog audience at APEC in Tampa, FL this year. Texas Instruments will have Bob Mammano at their booth at APEC where you can meet him and enter ...

Power electronics took centre stage at productronica 2025, underlining the sector’s pivotal role in the shift toward electrification, energy efficiency and advanced manufacturing, as Neil Tyler ...

The world of power electronics has changed over the decades as the products they power have evolved. For several decades, it was PCs and servers. Then, a massive influx of portable electronics, ...
