New Book on Power Converters and AC Electrical Drives with Linear Neural Networks from CRC Press

The first book of its kind, Power Converters and AC Electrical Drives with Linear Neural Networks systematically explores the application of neural networks in the field of power electronics, with particular emphasis on the sensorless control of AC drives. It presents the classical theory based on space-vectors in identification, discusses control of electrical drives and power converters, and examines improvements that can be attained when using linear neural networks.

The book integrates power electronics and electrical drives with artificial neural networks (ANN). Organized into four parts, it first deals with voltage source inverters and their control. It then covers AC electrical drive control, focusing on induction and permanent magnet synchronous motor drives. The third part examines theoretical aspects of linear neural networks, particularly the neural EXIN family. The fourth part highlights original applications in electrical drives and power quality, ranging from neural-based parameter estimation and sensorless control to distributed generation systems from renewable sources and active power filters. Simulation and experimental results are provided to validate the theories.

Written by experts in the field, this state-of-the-art book requires basic knowledge of electrical machines and power electronics, as well as some familiarity with control systems, signal processing, linear algebra, and numerical analysis. Offering multiple paths through the material, the text is suitable for undergraduate and postgraduate students, theoreticians, practicing engineers, and researchers involved in applications of ANNs.

Solderable PC BreadBoard, matches 400 tie-point breadboards with Power Rails

The SB400 Solderable PC BreadBoard enables you to transfer your circuit and wires from a plug-in breadboard without recutting wires or changing your layout. The SB400 has the same pattern and spacing as a standard 400 connection point solderless plug-in breadboard. It has a standard 5-hole strip for each IC pin, just like solderless breadboards plus power rails. However, it has the advantage that soldered joints provide a more reliable long-term connection than solderless contacts. The SB400 has four power rails like solderless breadboards, plus two bonus rails for power or signals. There are bonus two-hole pads along the centerline allowing DIL (dual in-line) headers to be used.

Last-modified  researchers found that you may have been created from the way current charging cell phone and capture the microwave signals and turn them into power microwave signals. From the Duke University team said the technology they were using solar panels more efficient and had been. Capture and devices Metamaterials wave energy they created various forms, use the conversion of other applications. In the future, satellite, sound or Wi-Fi signal able harvest, according to researchers in the United States. ' Is showing. You can avail of these consumer applications in materials ' engineering students Alexander Katko said.

By using glass fibers on the circuit board with copper conductors, researchers 7.3 volts of electricity into microwave oven will be. Offer to charge battery USB charger, mobile phone and camera frequently used about 5 volts. "We were aiming for the best we can achieve energy efficiency" said Allen hawks team members. "Energy efficiency we were getting about 6-10% in this design to 37% in solar cells what to achieve and was able to dramatically improve the energy conversion is on equal footing." Metamaterials are artificial materials to display properties in nature not normally seen.

Alexander Katko and Allen hawks design power harvesting devices. Building of the two students and their colleagues Steven camer phone and technology in the future can hope. Mobile phone when not in use so that to charge wirelessly. And that can help users who live in remote areas they are without access to the power grid also believe. They are "" be able to harvest energy from the signal generated by the cell phone towers. "Our work shows easy and inexpensive approach to harvest electromagnetic force", said Mr. Cummer. "Beauty of the design is basic building blocks is a self-contained and additives. Increase the cleaning power that can be assembled in just one more blocks. " Full report will be published in the December journal applied physics letters.

Corning Willow Glass used to make flexible solar power roofing shingles, could lower the cost of solar power significantly

The US government’s National Renewable Energy Laboratory has built flexible solar cells out of Corning’s Willow Glass. These new solar cells are strong enough that they could eventually replace roofing shingles, which would significantly shrink the biggest barrier to mass adoption of solar power: the cost of installation.

As you probably know, Corning is the manufacturer of Gorilla Glass, which furnishes the front of many smartphones, including the iPhone, and most HTC and Samsung devices. (See: Gorilla Glass coming to cars, making them more resilient and efficient.) Gorilla Glass is essentially a variety of alkali-aluminosilicate toughened glass that has been engineered for a combination of desirable factors (high strength and toughness, while remaining thin and light).

Willow Glass, on the other hand, is a flexible, transparent, thin (0.1mm) borosilicate glass that’s intended to be used as a substrate — a material on which other components, such as LCD or OLED electronics, can be laid down. Being a borosilicate glass, Willow Glass – just like Pyrex, which was developed by Corning in 1915 – is very heat resistant, which is useful when the creation of modern displays can involve temperatures measured in hundreds of degrees Celsius. Most importantly, though, Willow Glass is flexible enough to be rolled up and used in continuous roll-to-roll processes. It is this last point that is most exciting to display manufacturers, as it could significantly speed up production and reduce costs.

Willow Glass’s flexibility may lead to bendy or wraparound displays, but it’s important to note that you still need another layer to protect the Willow Glass (Corning recommends Gorilla Glass, of course). At just 100 micrometers thick, Willow Glass is flexible, but it isn’t strong like Gorilla Glass. If you’re waiting for a bendy device, devices that use plastic displays, such as LG’s plastic e-ink display, are probably a better bet. Willow Glass’s combination of flexibility, transparency, and heat resistance does make it a very good option for the creation of cadmium telluride solar cells, however.

Cadmium telluride photovoltaic cells are the only thin-film photovoltaic technology that’s cheaper than crystalline silicon — but until now, there hasn’t been a transparent substrate that also has the thermal resistance to withstand manufacturing. The DoE’s National Renewable Energy Laboratory (NREL) is reporting that it has built cadmium telluride (CdTe) solar cells on Corning’s Willow Glass (pictured right). For now, these are very small cells, but they could be used as roofing shingles. If production of these cells can be scaled up roll-to-roll processing, it would be possible to create very cheap solar power shingles that could be used instead of conventional asphalt, brick, or slate shingles.

When it comes to adopting solar power, the cost of installation is one of the most prohibitive factors. While solar panels themselves generally cost less than $1 per watt, the cost of installation can be five or 10 times that amount. Instead of paying a huge amount to have solar panels installed on your roof, it would be much cheaper if new houses were simply built with roofing made of solar panels. It would be rather exciting if each home produced the electricity that it required — in sunny climes, at any rate. (See: NASA’s cold fusion tech could put a nuclear reactor in every home, car, and plane.)
