The MTU2 Series of miniature surface mounted 2-W DC/DC converters from Murata Power Solutions (Mansfield, MA) is believed to be the industry's smallest 2-W converter and measures 8.2 mm x 8.4 mm x 8.5 mm with a 0.69 cm2 footprint and presented as being 50 percent smaller than
Central Semiconductor Corp. (Hauppauge, NY) introduced several new 600-V HyperFast Rectifiers designed for extremely fast switching applications, such as Power Factor Correction (PFC), where total conduction losses must be minimized and at the same time, power density must be maximized. The series
The HCS Series shunt resistor from Stackpole (Raleigh, NC) uses a solid metal element that is elevated off the mounting plane. This elevated design increases the ability of the part to dissipate the heat into the ambient air and not into the PCB. The HCS2512, for example, will
D-Wave – a special computing machine with this name has been getting computer scientists and physicists talking for a number of years now. The Canadian technology company of the same name is advertising the machine as a quantum computer.
In recent years, mini wind energy has been developing in a spectacular way. According to estimates by the WWEA-World Wind Energy Association, the level of development of the mini wind energy industry is not the same as that of the wind energy industry, although forecasts are optimistic.
Transphorm Inc. (Goleta, CA) announced 600V GaN (Gallium Nitride)-based, low-profile PQFN products and the expansion of its product portfolio in the industry-standard TO220 packages. The 600-V GaN HEMTs (high electron mobility transistors) use the
Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket. One approach they are trying involves designing circuits based on electronic fibers, known as carbon nanotubes (CNTs), instead of rigid silicon chips.
Excelsys Technologies’ (Cork, Ireland) UltiMod and Xgen families of power supplies are compliant to SEMI F47, an essential standard requirement for Semiconductor Processing Voltage Sag Immunity. The UltiMod and Xgen families meet the required
Imagine powering your cell phone by simply walking around your office or rubbing it with the palm of your hand. Rather than plugging it into the wall, you become the power source. Researchers at the 247th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, presented these commercial possibilities and a unique vision for green energy.
Linear Technology Corporation (Milpitas, CA) announced the LT3752/LT3752-1, a high input voltage capable synchronous forward controller with active clamp transformer reset. A controlled VOUT start-up and shut-down is maintained using
Sales of electric vehicles (EVs) nearly doubled in 2013, but most won't take you farther than 100 miles on one charge. To boost their range toward a tantalizing 300 miles or more, researchers are reporting new progress on a "breathing" battery that has the potential to one day replace the lithium-ion technology of today's EVs.
Texas Instruments introduced two flyback power solutions that are said to achieve the highest energy efficiency and lowest standby power consumption for 5-W to 100-W AC/DC power supplies. The UCC28910 switcher with integrated
A nuclear waste repository must seal in radioactive waste safely for one million years. Researchers currently have to study them and their processes in real underground laboratories but a virtual underground laboratory will soon simplify their work.
As the United States continues to lead the world in the production of natural gas, scientists from the Florida campus of The Scripps Research Institute (TSRI) have devised a new and more efficient method with the potential to convert the major components found in natural gas into useable fuels and chemicals—opening the door to cheaper, more abundant energy and materials with much lower emissions.
America's current energy boom may take a new direction thanks to the discovery of a new way to turn raw natural gas into upgraded liquid alcohol fuel. In the March 14 issue of Science magazine, chemists from Brigham Young University and The Scripps Research Institute detail a process that could reduce dependence on petroleum.
Mornsun has launched the IF/B_XT-1WR2, F/B_XT-2WR2, F_D-1WR2, R2 series of DC-DC converters. Compared with the old generation, they have improved on efficiency, no-load power consumption, and short-circuit protection. They also feature compact size....
Micrel (San Jose, CA) announced that it would be previewing the MIC2111 DC/DC multi-mode controller at the Applied Power Electronics Conference and Exposition, APEC 2014. The industry conference will be held March 16-20, at the Fort Worth Convention Center.
The Energy Department’s National Renewable Energy Laboratory (NREL) has developed a web-based tool to help consumers better understand the energy performance of building-related products. The Technology Performance Exchange™ (TPEx™) is a portal that helps manufacturers and other organizations that measure and test products easily share performance data with product consumers.
GIGAVAC (Santa Barbara, CA) announced two additions to its High Voltage Contactor line of advanced switching solutions. The HX21 and HX200 join the HX22 as the smallest UL508 recognized contactors for high current switching at 1000 VDC, according to the company. The series can
Who needs a gun when you have CUPID? And by Cupid, I don’t mean that fat cherub that comes out around February 14th to shoot people with arrows — though the shooting part isn’t that far off. This CUPID, which stands for Chaotic Unmanned Personal Intercept Drone, is actually a personal security safety UAV.
Infineon Technologies AG (Neubiberg, Germany) is launching a high-precision current sensor, which requires only a sixth of the board space taken up by existing sensors on the market today, according to the company. Using the TLI4970, it is possible to measure
