Fujitsu Laboratories has developed a GaN power transistor for mains PSUs, claiming it to have the highest current density yet.

QuantaSol's record-breaking solar cell is GaAs-based with multiple quantum wells to broaden its absorption spectrum, and is made in the UK.

Imperial Collage spin-out QuantaSol is claiming a single-junction solar cell world record. The strain-balanced quantum-well solar cell recorded an efficiency of 28.3% when exposed to 500sun concentrated illumination.

Dyson has gone to 104,000rpm brushless DC technology to combine efficiency and manufacturability in its latest handheld vacuum cleaner.

Essex-based XP Power has introduced a 95% efficient 250W AC/DC power supply, the CCM250.

The TPS54620 is designed to fit a complete 6A power design with inductor and capacitors in less than 195mm square

A magnetic robot 'ferret' is to search cargo containers at UK ports, if a project at the University of Sheffield goes to plan. Funded by the Engineering and Physical Sciences Research Council (EPSRC), the requirement came out of the UK Boarder Agency (UKBA) which is looking for alternatives to unpacking suspect containers, at least for preliminary searches.

ARM will be one of a number of specialists in power efficient design speaking at the Electronics Weekly Live Design Conference which is taking place at National Electronics Week in Earls Court 2, London on Wednesday June 17th

Denver-based Infinite Power Solutions is claiming 15,000 deep discharge cycles for its postage stamp battery technology, as well as 45mA/cm2 current density.

SunEdison has initiated field trials in California using National Semiconductor's SolarMagic power optimisers, which are designed to enable individual solar panels to maximise energy-produced independent of performance of other panels in an array
