MPD’s BK-53 surface mounting AA battery clip uses two spring arms to capture and hold a AA battery in place. These arms are said to make it easy to insert and remove a AA battery because of the desirable access afforded. Normally used in pairs, the clips are
Microchip Technology Inc., expanded its 16-bit dsPIC Digital Signal Controller (DSC) portfolio for digital power-conversion applications. Eight new dsPIC33F ‘GS’ Series DSCs provide up to four times the memory, compared to Microchip’s existing SMPS and digital power conversion families. Additionally, these DSCs can
ON Semiconductor introduced five CMOS linear voltage regulator families. The NCP69x families are optimized for use in low current consumption portable battery-powered and ‘always on’ applications such as cable modems, satellite receivers, digital-set-top boxes and electricity meters. The NCP690, NCP691, and NCP692 are
Venkat Selvamanickam, director of the Applied Research Hub at the University of Houston, is developing a technology with high temperature superconducting wires that promises to revolutionize the way power is generated, transported and used.
Micropelt has collaborated with Royal Dutch Shell to prove the concept of converting waste heat into a sustainable, maintenance-free power supply for wireless sensor devices.
Materials scientists at the University of Wisconsin-Madison have designed a way to harvest small amounts of waste energy and harness them to turn water into usable hydrogen fuel.
While much of the Energy Star program is sound, and has led to real quantifiable energy savings over time, over the last four years, alarm bells have been sounding on the increasingly lax certification process.
Absopulse’s FLP 09R DC/DC converter series is designed for low power railway requirements. With a height of 20 mm, this 25 W unit is suitable for applications with stringent space restrictions.
The statistics vary, but all seem to be in agreement that nearly 30 to 40% of the present load base on the grid is caused by induction motors

There is no question the overwhelming majority of ‘mechanical’ energy utilized in this country has as its source the output of Heat Engines, i.e. devices that convert stored solar energy in fossil fuels to ‘mechanical work’.
The New York State Energy Research and Development Authority recently announced a total of $8 million in research grants to help develop or commercialize energy-storage projects.
What is the next breakthrough in battery technology?
Efficient Power Conversion Corporation (EPC) today introduced a family of enhancement mode power transistors based on Gallium Nitride on Silicon technology.
MicroPower Direct’s LF500RW Series of SMT 5 W DC/DC converters provides a wide 2:1 input range, tight line/load regulation, output power/overload protection and low noise operation. Twenty-one models operate from wide 2:1 inputs of
A major challenge facing power engineers today is how to overcome a reduction in board space for the power circuitry in commercial electronic products. A quick walk through any electronics retail store will reveal that personal computers have become smaller and even miniaturized which is a trend for many other types of electronic devices.
Portable products increasingly rely on a single 3.7V Li-Ion battery for the energy source. For these and other low-voltage applications, lower gate voltage power MOSFETs improve the efficiency for extended battery life and reduce the heat dissipation involved in switching the loads. In addition, they simplify the design of numerous control functions by allowing direct control / drive.
This year at APEC I moderated a rap session on dealing with the Smart Grid. It had a standing-room-only crowd, and demonstrated how much interest exists on both the technical and political issues involved.
