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

Binder-USA has announced the release of a T-shaped splitter for the Series 870 7/8” connectors. The T-splitter is used to connect several devices for a power supply or a bus connection. Designed for DeviceNet applications, the 7/8” connectors are
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.
TT electronics IRC’s MHP Series power resistors feature power ratings from 20 W to 600 W in industry standard TO-220, TO-247 and SOT-227 transistor-style packages. The resistors provide

I recently had the great honor of moderating the Smart Grid Rap Session at this year’s Applied Power Electronics Conference (APEC). It brought home to me that in addition to the technical challenges facing the power industry, there are also political issues that must be addressed as we move forward. The old political arguments around power revolved around NIMBY issues about the location of power plants...
