An Antarctic suspense story has come to an end with one of the largest icebergs ever observed breaking off the Larsen C Ice Shelf. The slow-motion breakup was closely monitored by scientists, who say that the 6,000 km² (2,300 mi²) ice floe now adrift in the sea is 190 m (625 ft) thick and represents 10 percent of the shelf.
 How to Fast-Charge Your SupercapacitorSponsored by Analog Devices Supercapacitors (or ultracapacitors) are suited for short charge and discharge cycles. They require high currents for fast charge as well as a high voltage with a high number in series as shown in two usage cases: an automatic pallet shuttle and a fail-safe backup system. In these and many other cases, the fast charge is provided by a flexible, high-efficiency, high-voltage, and high-current charger based on a synchronous, step-down, supercapacitor charger controller. |
