How to improve power supply energy efficiency
Improving power conversion efficiency is important for saving energy in power supplies. There are many discussions in the field about achieving higher efficiency by implementing techniques such as a digital control loop, using better components, innovative packaging, or optimising thermal management
How to extend battery life with soft-start circuitry
Implementing a soft-start routine eliminates the problems caused by inrush current, as it allows the current to build up over a controlled period of time to the required value
Solar cells can ‘significantly’ extend mobile battery life – Sharp
Sharp plans to expand its family of LROGC02 type solar components for mobile applications to five models to address this market. These have an efficiency of 13% and the low mounting depth of 0.8mm
Bosch acquires two solar energy system firms
“With aleo solar and Johanna Solar, we are strengthening our photovoltaics business by completing our value added chain and opening up new distribution channels,” said Holger von Hebel, president of the Bosch Solar Energy division
Using iPhone app to dim the LED lights
The system was to be programmed using standard PC interfaces, but we also set ourselves the challenge of creating an iPhone application as an alternative. The project also demonstrates the efficacy of a power line control protocol that runs over a 24Vdc line
TI unveils industry’s first 12bit 1Gsample/s ADC
Texas Instruments has unveiled industry's first 12bit 1Gsample/s ADC, the ADS5400. A buffered front-end simplifies external circuit design, and fast sampling means up to four can be used together for 4Gsample/s and 2GHz bandwidth.
Power supply makers target LED PSUs
AC-DC power supply makers are introducing constant-current models for lighting manufacturers moving into the LED illumination market.
Dialog has record Q3
The power management specialist had net profit in Q309 of $8.8m, representing 14.8% of revenue compared to $3.3m in Q209. Total cash increased in Q309 by $2.9m to stand at $46.4m.
Stealth wind turbines can’t be seen in Norfolk
The five year project has developed ‘Stealth Turbine’ technology that can significantly reduce the size of the radar signature made by individual turbines to the point where they can be effectively ‘factored out’ of air traffic control and air defence systems
