Choosing the right DC Power Supply for your Application by Bob Preville
The DC Power Supply is a rather fundamental electronic device, however there are hundreds of DC Power Supply products on the market from dozen of manufacturers. Narrowing down the best product for your application and budget can be a daunting task. This article addresses DC Power Supply... Realistically, no power supply is 100% efficient because power conversion always results in energy loss, usually in the form of heat dissipation. ... Choosing the right DC power supply for your application requires definition of some basic design specifications: voltage range, current range, number of...

Testing Transformer - 3 Proven And Simple Methods To Test Transformers by Jestine Yong
Testing transformer is very easy if you follow the procedure explained in this article. Generally there are two types of transformer in the market i.e. the linear type and the switch mode power transformer. In this article I’m only explain on how to test the linear transformer. ... For some transformers like the UPS (uninterruptible power supply) you need wiring diagrams to assist you because there are so many secondary windings and you may get confused. ... Lastly, checking switch mode power transformer is different from testing linear transformer.

Testing a Transformer- How To Accurately Test A Transformer by Jestine Yong
There is two types of transformers in the market- linear transformer and switch mode power transformer. The transformers design is different. Sometimes it is just referred as ac transformer. Linear transformer mostly used in radio, project kits, VCD and etc while switch mode transformer can be... Swith mode power supply are designed to run with load while linear transformer can be test without load. ... You cannot apply ac voltage to the equipment and expect the desire output at the secondary side without connect to load otherwise over voltage will happen (because you have removed all the...

Integrated Power Management Circuits by Dan Hagopian
Discussing internal battery design would be incomplete if we did not write on the subject of integrated circuits. Batteries for PDAs, MP3s, Digital Cameras, and Laptops have designed within them integrated power management circuits that insure that the deliverance of reliable power is properly... Supervisory circuits are known by a variety of names, including battery monitors, power supply monitors, supply supervisory circuits and reset circuits. ... They perform critical functions including power-on-reset (POR) protection to ensure that processors always start at the same address during...

Top Strategies to Maximize the Life of Your Hard Drive by Alex Bezborodov
If I asked you the question: which part of your computer is the most fragile, what would you say? What if I asked: which part is most important to you? Often, the answer to both of these questions is your Hard Drive. Your hard drive is likely one the most important things you own. ... An electrical failure can be caused by a power surge, lightening strikes, power brown-outs, incorrect wiring, a faulty or old power supply, and many other factors. ... The best way to protect your computer from such dangers is to use a highly rated protected power bar or an Uninterruptible Power Supply (UPS).

Marine Electronics by Ken Jones
Autopilots The first self-steering gear was introduced in the 1920's to control model yachts but it was not until 1948 that the principle was applied to full scale yachts. Standing at the helm for lengthy periods, monitoring instruments and keeping a good look out can be very tiring. ... VHF Radio The power required to transmit is minimal, all sets have the option of transmitting on either 1 Watt or 25 Watts and the lower power should be used whenever possible. ... The mechanical power is applied to the rudder by either electric linear activators, hydraulic pumps or rotary drives.

Grid Computing by Sandro Azzopardi
Most industries today have become so dynamic that organisations have to consistently seek and adapt to change, in order to survive and prosper. Factors like more diversified customer preferences, technological advances, increased competitive threats and an intensified global economy are among... Whilst technology tends to evolve in a non-linear fashion, Moore's Law has ensured that processing power has been increasing exponentially. ... So the inevitable questions are, is it really feasible to increase and upgrade the firm's single source of computational power if most of the time the...
