Employing dyes that trap wavelengths of light inside the pane, the technology can increase the power from solar cells by 40 times, according to the MIThttp://www.edn.com/article/CA6586238.html?rssid=237 Lithium-ion technology targets portable power- August 21, 2008 Work closely with your lithium-ion-cell manufacturer and battery-pack-design house to develop safety and performance features for your system's battery pack.http://www.edn.com/article/CA6586222.html?rssid=237 Integrated ORing controller and MOSFETs run fast and cool for redundant supplies- August 14, 2008 In their quest for near-100% uptime, designers of high-availability-system applications, such as telecom and datacom servers, employ redundant power systems: If one power supply fails, a redundant supply can pick up the load. Redundant- and backup-power supplies enter the load along with ORing MOSFETs, which ideally should have a minimal on-state resistance and fast dynamic response to power source failures.http://www.edn.com/article/CA6587562.html?rssid=237 High-voltage, low-noise dcdc converters- August 7, 2008 You can make a 1-kV dcdc converter with only 100 µV of noise.http://www.edn.com/article/CA6582859.html?rssid=237 MIT researchers use plant energy storage system for solar storage innovation- August 1, 2008 In what MIT researchers say is a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, the researchers report they have discovered a way to store energy for use when the sun doesn't shine, thereby overcoming a major barrier to large-scale solar power. "This is the nirvana of what we’ve been talking about for years,” MIT's Daniel Nocera says.http://www.reed-electronics.com/electronicnews/article/CA6583673.html?rssid=237 |
