Scientists have discovered that caffeine can help make a promising alternative to traditional solar cells more efficient at converting light to electricity. Their research may enable this cost-effective renewable energy technology to compete on the market with silicon solar cells.
South Australia has received another boost in its battle for improved power security following the completion of a new 30-megawatt battery on the Yorke Peninsula. Key points: The battery is to provide power to the Yorke Peninsula region of SA It can provide back-up power to 4,500 customers in the region The storage facility took more than 30,000 hours to
Why have batteries become important? In a world increasingly anxious about climate change, the surge in the generation of renewable energy over the past 20 years offers a sliver of hope. But the variable nature of wind and solar power means that storing energy until consumers need it has become the next big challenge. And so, large-scale battery installations are
Your knees and your smartphone battery have some surprisingly similar needs, a professor has discovered, and that new insight has led to a ‘structural battery’ prototype that incorporates a cartilage-like material to make the batteries highly durable and easy to shape.
Stanford University Professor Hongjie Dai and colleagues have developed a high-performance aluminum battery. And they use Neware battery testers in their daily research work. Stanford University scientists have invented the first high-performance aluminum battery that’s fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many commercial batteries in wide use today. “We have developed a rechargeable aluminum battery
ROHM is announcing the availability of a 12- to 76-Vdc input, 3A variable output voltage, dc-dc buck converter with integrated 76V MOSFET optimized for high power (high voltage x large current) applications such as motors, factory automation equipment, communications infrastructure, and industrial machinery. The BD9G341AEFJ utilizes ROHM’s high-voltage 0.6um BiCDMOS process to achieve a maximum breakdown voltage of 80V (the
Linear Technology Corporationannounces the LTC3884, a dual-output current-mode synchronous step-down dc-dc controller with programmable loop compensation and I²C-based PMBus interface. This device enables the use of very low dc resistance (DCR) power inductors (0.3 milliohms) by enhancing the signal-to-noise ratio of the current sense signal to maximize converter efficiency and increase power density.

The HCS Series from Stackpole now includes an 0.2 milliOhm resistance value in the 3920 and 5930 chip sizes. This extremely low resistance value allows higher power current sensing with greater efficiency. In addition, the all-metal raised element means lower PCB temperatures due to increased convection under the part. The HCS typically runs 15 to 30 degrees C cooler than
Artesyn Embedded Technologies today launched the ADQ500 series, new 500-Watt quarter-brick isolated dc-dc converters with the high efficiency and thermal performance demanded by telecom network and data center equipment. ADQ500 series converters are Artesyn’s first to have both a digital interface version and an analog interface version, with both following the industry standard DOSA footprints. The digital interface version allows
Analog Devices, Inc. today introduced a 24-bit data acquisition system-on-chip (SoC) series designed to improve the performance of protection, monitoring, and power quality measurement equipment used to manage transmission and distribution (T&D) within smart grid systems. The AD7770 enables higher performance and smaller form factor protection relays, while the AD7771 enables power quality measurement equipment to provide early detection of
