Choosing the right power supply design is imperative for an overall successful product. With the ongoing goal of increased density, reliability and efficiencies, power ratings need to be reviewed carefully. Product life, temperature, input voltage, load and cooling are vital considerations as is meeting standards for safety, EMC and regulatory environmental impact compliance.
An MIT researcher has developed a technique that provides a new way of manipulating heat, allowing it to be controlled much as light waves can be manipulated by lenses and mirrors. The approach relies on engineered materials consisting of nanostructured semiconductor alloy crystals. Heat is a vibration of matter —
"Smart" watches that talk to cellphones have been around for some time, but they've been hampered by their high battery drain - usually needing recharging every few days.

High voltage battery simulator and test systems are essential for conducting testing of the high voltage DC power systems that are such a critical element of electric (EV) and hybrid/electric (HEV) vehicles. To accurately test a high voltage hybrid
The storage capacity of concentrating solar power (CSP) can add significant value to a utility company's optimal mix of energy sources, a new report by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) suggests.
Murata Americas introduced its DMF series, a high peak current electrical double-layer capacitor (EDLC). The newest EDLC offering from Murata also features low resistance (40mΩ to 60mΩ) and stable temperature characteristics, enabling it to be charged and discharged frequently over the operating range of -30°C to +70°C
Why are efficient and affordable solar cells so highly coveted? Volume. The amount of solar energy lighting up Earth's land mass every year is nearly 3,000 times the total amount of annual human energy use. But to compete with energy from fossil fuels, photovoltaic devices must convert sunlight to electricity
When I first learned of Pecan Street, Inc. and the Smart Grid Demonstration Project, I knew little of the consortium’s mission. I had heard of smart grids before, but I was curious to know more about what the Pecan Street’s project was and how it was significant to the advancement of “green” technology.
GreenPeak Technologies announces the GP690, adding ZigBee PRO to its product portfolio and offering full support for its Open Smart Home Framework, integrating all three ZigBee networking variants Green Power, RF4CE and PRO into a single overall architecture defining the “second wireless network for the home”.
Wind power will make a major contribution to the energy turnaround. Efficient power generation by means of offshore power plants requires powerful, reliable generators that do not cause disproportionately high logistic efforts and do not require complex foundations
Green schemes to fight climate change by producing more bio-fuels could actually worsen a little-known type of air pollution and cause almost 1,400 premature deaths a year in Europe by 2020, a study showed on Sunday. The report said trees grown to produce wood fuel - seen as a cleaner
As consumer, commercial and industrial electronic systems become more advanced; they require more precise and reliable power sources to function at optimum levels. System integrators and designers are turning to more sophisticated power distribution units (PDUs) with customized specifications to better tackle power hurdles.
Answering the question, “How low can you go with power?” Texas Instruments Incorporated introduced the industry’s lowest power DC/DC step-down converter, which increases the amount of harvested energy an end application can use as much as 70 percent over alternative devices.
Power Sources Unlimited, Inc. announced a new 360-W, high-efficiency CFM361S Series of AC/DC power supplies. These units are suitable for telecom, ITE and industrial equipment applications. The CFM361S Series consists of single 12-V, 24-V, and 48-V output models with
