Figure 1: Typical Isat and Irms Ratings

­Inductors function as circuit elements by reaction to current flow in the windings. Inductors are fundamentally current-driven devices, and anyone who has designed a dc-dc converter knows power inductor datasheets are covered with Irms and Isat current ratings. Picking a power inductor is all about current ratin

Collision Risk and Habitat Loss: Wind Turbines in Forests Impair Threatened Bat Species

Dr. Christian Voigt, bat specialist from the Leibniz Insitute for Zoo and Wildlife Research, conducting fieldwork at wind energy sites in Brandenburg forests, Germany

­In order to meet climate protection goals, renewable energies are booming – often wind power. More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites. Thus, forests are coming into focus as potential si

Raising Green Hydrogen Extraction Efficiency

A large lens concentrates sunlight onto the water-splitting catalyst. Outdoors, the device was ten times more efficient than previous efforts at solar water splitting.

The single biggest problem currently with renewable energy is that the sources are not consistent or predictable. A cloudy or windless day and less energy is generated, and the power grid has to be supplemented by other means. Most of these other ways of generating power, such as coal, oil and natural gas are major co
