When it comes to circuit protection, the first line of resistance is resistance. Resistance limits current flow and resistance, in conjunction with capacitance, slows the rate of increase of voltage, giving other protection measures in the circuit time to act. But, resistance has its drawbacks. If the current through the resistance is significant, it wastes power....

Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor – meaning that it could be used to make "spintronic" devices, which rely on magnetic force to operate, rather than electrical currents.
For many of us, it’s the fuel that wakes us up and gets us started on our day. Now, University of Cincinnati researchers are discovering that an ingredient in our old coffee grounds might someday serve as a cheaper, cleaner fuel for our cars, furnaces and other energy sources.
A University of California, Riverside assistant professor of electrical engineering and several colleagues have created a new measurement tool that could help avoid an energy crisis like the one California endured during the early 2000s and better prepare the electricity market for the era of the smart grid.
Commercial uses for ultraviolet (UV) light are growing, and now a new kind of LED under development at The Ohio State University could lead to more portable and low-cost uses of the technology. The patent-pending LED creates a more precise wavelength of UV light than today’s commercially available UV LEDs...
Researchers from the University of Pennsylvania have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications.
Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution, but a new study from Stanford University suggests that might not always be the case.
Schaefer Inc. announces the addition of the MTQZ75 Series by Minmax to its wide-ranging power product portfolio. The MTQZ75 Series is a 75W dc-dc converter designed specifically for mission critical transit and railway solutions. MTQZ75 Series is a new generation of high performance dc-dc converter modules designed predominantly for applications in the railway industry....
We love to interact with our engineering community at ECN, and we’re always interested in learning about the different trends and new technologies our readers are working on!
