Power YouTube videos support power converter adoption

Power YouTube videos support power converter adoption 28th January 2014 Ericsson has put together videos to promote its 3E PSU portfolio, showing potential adopters how to use the firm’s Digital Power Designer on-line tool. “With built-in digital control and monitoring, the 3E series includes isolated bus converters and digital point-of-load [POL],” said the firm. “The latest version of Digital Power Designer inclues a number of features that enable board power designers and system architects to simulate either simple or complex power schemes. Version 1.4 features loop compensation functionality that makes it easy to simulate output capacitors and output filtering networks such as PI filters, and to optimise loop response without hardware modification for the end application.” There is also the 3E Design Toolbox which includes five boards supporting power interface modules, bus converters, current sharing, single-in-line 3E POL regulators and a generic board accommodating thro...

Power Formula 1 cars more hybrid than hybrids from today

Power Formula 1 cars more hybrid than hybrids from today 28th January 2014 2014 Renault Formula1 engine 400 For the 2014 season, Formula 1 cars will have smaller engines, plus two ‘energy recovery systems’ (ERS): regenerative braking, like most road hybrids, and an exhaust gas-driven electrical generator – the kind of electrically-enhanced turbo charging that has yet to reach road cars. Regenerative braking is not new to Formula 1. Hybrid technology was first introduced to the race series in 2009 with ‘Kinetic Energy Recovery System’ (KERS), whose influence has been increased by regulation over the years. However, today is the day when cars both ERS systems, and far more energy storage, start pre-season testing in Jerez, Spain. “The 2.4 litre normally-aspirated V8 engines of 2013 produced around 750bhp, with an additional 80bhp available for around six seconds per lap from KERS. The 2014 V6s put out around 600bhp. However, the two ERS systems (ERS-K and ERS-H) will give driver...

Research Space: Dream Chaser mini shuttle gears up for first orbital flight

Research Space: Dream Chaser mini shuttle gears up for first orbital flight 28th January 2014 NASA astronauts may be getting a sweet new ride. Engineers at Sierra Nevada Corporation have announced that the Dream Chaser will make its first orbital flight on 1 November 2016. The Dream Chaser will launch attached to an Atlas V rocket as shown in this artist’s impression. In previous flight tests, the craft was “flown” suspended from a helicopter. Its first free flight ended badly when it crash-landed after successfully gliding on autopilot from an altitude of 3.8 kilometres. The Dream Chaser is one of three spacecraft vying to replace NASA’s retired space shuttle and restore the US’s ability to send astronauts into orbit. Currently, astronauts must hitch a ride to the International Space Station in Russian Soyuz capsules. Other contenders being developed with NASA’s support are Boeing’s CST-100 and SpaceX’s Dragon. Although the Dream Chaser is small – about 9 metres long, compare...

Information Technology Solar charger for iPhones is a Kickstarter hit

Information Technology Solar charger for iPhones is a Kickstarter hit 28th January 2014 San Diego-based start-up StrongVolt has raised $52,000 on Kickstarter crowd-funding site for its iPhone and iPad solar charger. The charger consists of multiple panels which fold up into a “pocket-sized” format. Dubbed SmartCharger, it uses patent-pending technology developed by the start-up which allows the solar charger to automatically reconnects after passing under clouds or shade and is specifically designed for iDevice compatibility. These are different power verison of the charger ranging from 3W to 18W. The 18W version (28.5″x12.5″x0.2″) charges an iPhone in one and a half hours and the 5W version (15.4″x7″x0.2″) charges an iPhone in three and a half hours, according to StrongVolt. “Apple iDevices such as iPods, iPhones and iPads are notorious for not working with existing solar chargers because they require a constant and stable power source,” claimed StrongVolt. “The SunTrack tech...

Business Tablet processors on a roll

Business Tablet processors on a roll 28th January 2014 300m tablet  processors will ship in 2014, says IHS, very close to the 315 million x86 PC processors shipped last year according to IC Insights. Last year 243.1 million tablet processors were shipped, says IHS, and by 2016 400 million a year will ship. ‘The main challenge facing Intel will be how to compete in the entry-level segment,’ says IHS. Intel will be up against Chinese chip manufacturers Rockchip, Allwinner, and Amlogic and Taiwanese chip-maker Mediatek, all of which are used to cut-throat competition on price – and some of the Chinese tablets sell for $50. Intel is planning to pay tablet manufacturers to use its chips – a strategy which is likely to cost Intel upwards of $800 million this year. That’s on top of the losses, estimated at $2.5 billion, which Intel made trying to sell mobile processors last year. ‘One major advantage for the Chinese is the capability to produce turnkey chip solutions ready for deploy...

Sensors Digital colour sensing chip is tiny 27th January 2014 Intersil colour sensor Intersil has announced a light-in digital-out colour photometric chip. Called ISL29125, and measures only 1.65×1.65mm, it is intended to be used alongside displays, monitoring ambient light so the perceived display colour and intensity can be maintained. “Specifically, in OLED display TV applications, it can be used to adjust the blue organic material ageing profile to maintain consistent contrast and brightness throughout the life of the display,” said the firm. Dynamic range is 5.7mlux to 10klux, in two ranges: 0.0057 to 375lux, and 0.152 to 10,000 lux, measured through an internal integrating 16bit ADC operating at 100ms/colour. Part-to-part variation of RGB output is said to be less than +/-10% Operating is over -40 to +85°C from 2.25V to 3.63V, using 85uA, or 0.5uA when shut down. The digital interface is I2C, needing pull-ups to between 1.7 and 3.63V. There is an evaluation board and a p...

Research Phosphorene: graphene with a bandgap

Research Phosphorene: graphene with a bandgap 2014/01/27 US and Chinese scientist have made transistors from a graphene-like substance called black phosphorus, which is being dubbed phosphorene in its few-layer form. Just like graphene, phosphorus can form a flat sheet molecule. Although up-close it is heavily corrugated while graphene is flat – the difference being a result of phosphorus’ three covalent bonds and carbon’s four. “The three bonds take up all three valence electrons of phosphorus so, unlike graphene, monolayer black phosphorus is a semiconductor,” said the Chinese team in its paper ‘Black Phosphorus Field-effect Transistors‘, published on arxiv.org. “For few-layer phosphorene, interlayer interactions reduce the band gap for each layer added, and eventually reach ~0.3eV for bulk black phosphorus.” In the bulk form, layers are held together by Van der Waals – also like graphene. For research, flakes of both materials can be removed from lumps of the raw material u...
