The high electrical currents of fast charging are forcing designers to invent standard techniques for predictably modeling heat and cooling. Dr. Michael Ludwig, T&C Core Technologies, TE Connectivity The only way electric vehicles (EVs) will ever catch on is if consumers can charge them up quickly. Consequently, manufacturers are developing high-power charging (HPC) schemes which […]

Myth busted: No, LEDs don’t get 50% dimmer after a year
A one-year burn-in test helps refute a small piece of fake news about LED bulbs. We’ve torn down a number of LED bulbs over the years to analyze their content and design strategies. But when we published some of our findings a little over a year ago, we got this missive in the comment section: […]
