KEMET has introduced a supercapacitor balancing development kit for its S301 family of 60mm diameter capacitors. Used in series, supercapacitors need electronics to ensure no capacitor goes over the rated voltage as the string approaches full charge – 2.7V in this case, see below. The kit includes two-stage active balancing circuits to ensure that voltage across each supercapacitor is approximately
Tectrol Europe announce the availability of their TFE-1800-48 1800W, 48Vdc output front end power supply designed in a sub-1U horizontal package for integration into a Tectrol power shelf or other end-user system. The power supply includes secondary isolation from chassis >1500Vrms with output adjustable to 54Vdc for PoE (Power over Ethernet) requirements and is suitable for ATCA (Advanced Telecommunications Computing
Linear Technology Corporation introduces the LTM8046, a 2.5W output dc-dc µModule® (micromodule) converter with 2kVac galvanic isolation (production tested to 3kVdc) in a 9mm x 15mm x 4.92mm ball grid array (BGA) package. A minimum creepage distance of 4.3mm on the package exterior supports operation at a working voltage up to 400VRMS in a pollution degree 2 environment. The isolated
A 200 mph Houston-Dallas bullet train is being planned by a private company called Texas Central Railway. The company’s CEO is Richard Lawless, who lived in Tokyo when he was a C.I.A officer in the 1980s and rode the Shinkansen bullet train. This train covers about 300 miles between Tokyo and Osaka averaging well over 100 mph for each trip.
One of the world’s biggest solar manufacturers and project developers, the US-based First Solar, has predicted that utility-scale solar costs in Australia will halve over the next five years, becoming cheaper than wind energy by 2020. First Solar says this should mean that large-scale solar takes up an increasing amount of the capacity required to be built under the current
The co-author of this article is Lutz Rauscher from Bosch Sensortec. Up until shortly before publishing this blog was entitled “Trends in MEMS orientation sensor form factor reduction.” That was until we ran the draft past a colleague for proof reading, and in her feedback she summarised: “So, what you are really questioning is does size matter, and if so
Semiconductor products for the automotive industry accounted for almost half of Infineon’s entire sales. With €510 million, this segment contributed 46% to the sales volume of €1.11 billion and 41% to the total segment result of €170 million. While Automotive continues to be the strongest segment for the chipmaker, sales and profit in the company’s Industrial Power Control (IPC) segment
Researchers from the Fraunhofer IISB institute for integrated systems and components therefore adopted a different approach: Within the project ‘Energy Campus Nuremberg’ they developed a system that allows charging the vehicle from the front side rather than from the bottom. The vehicle drives up to the charging coil, and since it can virtually close the gap in touching the charging
The researchers, working at various U.S. Department of Energy light source facilities as well as at Cambridge and Stony Brook universities, chose ruthenium oxide (RuO2) as a model system to study these so-called ‘conversion materials, named because they undergo large structural changes when reacting with lithium ions, reversibly forming metal nanoparticles and salts (here Ru and Li2O). The reactions are
Confirming a leadership position in the automotive market, today Texas Instruments announces that more than 15 million of TI’s advanced driver assistance systems (ADAS) System-on-Chip (SoC) devices are on the road. TI’s open and flexible solutions are in series production in over 25 OEMs and over 100 car models, and are designed to help reduce the number of road collisions
