Designers and end users now consider USB as a general-purpose, somewhat-universal charging source delivering up to about 100 Watts under best-case conditions (USB 3.1/Type C). We're seeing many application notes, articles, and ICs on managing the latest USB standard with respect to its power-d......

Robotics is hot these days, and it's certainly deserved. Today's robotic arms and systems are faster, cheaper, more precise, and lighter by large factors compared to those of even just a decade ago. The result is the deployment of these units in stationary and mobile applications that wer......

The upside is that I am repeatedly astonished at the performance and functionality that is packed into consumer products, and at an amazingly low price. The downside is that I fear this never-ending wave of providing so much more for so much less has been a major contributor to the low profession......

Debugging and troubleshooting are major parts of the engineer's world. I've always regarded them as the most difficult of engineering challenges because it takes a combination of factors: technical expertise, experience and practice, lessons learned from mistakes, ability to think in both ......

We are aware that switching power supplies (converters), whether AC/DC or DC/DC, are almost always more efficient than linear versions. We also know that the weight and size difference is also dramatic, as well as much more tangible and immediately apparent. But sometimes, you have to see the two ......

Power supply efficiency is a "hot" topic these days, whether it's an AC/DC or DC/DC unit (sorry about that unavoidable pun). Everyone is concerned about it for reasons related to issues of one or more factors of run time, thermal load, operating cost, or regulatory mandates. &nb......

Its well known that the performance and life of the traditional incandescent bulb performance are very sensitive and highly nonlinear in response to the nominal value of the AC line. Years of data on countless bulbs, plus some analytical work, has shown that for a supply voltage V near the ......

The phenomenal proliferation of wireless devices (Wi-Fi, IoT, handheld products) has forced engineers who don't have much RF background to become somewhat RF-knowledgeable and meet performance standards. Fortunately, in many cases, the required tests are well-defined, the needed equipment and ......

The increased interest in long-life embedded applications such as remote data logging or utility meters brings up the eternal engineering question: how are we going to power these devices? These devices should operate on a small battery for 10, 20, or more years without any attention, often under......

Its not news that LED-based bulbs are replacing the venerable incandescent bulb. In many jurisdictions, the basic incandescent bulb (especially for higher wattages) can no longer be sold; only specialty versions are still allowed. The basic bulb has served us well for over 100......
