  We might complain that it’s 2015 and we’re still waiting on our hoverboards. But if Nikola Tesla were alive today, he’d probably wonder where the hell our fuel-free, super-fast airplanes were. And who could blame him? Fuel-free planes aside, he actually predicted a lot of 21st century technologies quite accurately. The January 30, 1926 issue…

Linear amplifiers use transistors (MOSFET or similar) to increase the amplitude of an applied signal. Whatever signal is applied to the gate of the transistor is amplified but a constant factor called the amplifier gain. By contrast, a Class D amplifier is a type of amplifier which uses transistors as ON/OFF switches. The signal to…

Nikola Tesla vs. Thomas Edison: Who Was the Better Inventor ? By By Tia Ghose, Staff Writer 16 hours ago Nikola Tesla would have celebrated his 158th birthday today (July 10). The Serbian-American scientist was a brilliant and eccentric genius whose inventions enabled modern-day power and mass communication systems. His nemesis and former boss, Thomas Edison, was the iconic American…

Windham NH, MAY 22—CET Technology (www.CETTechnology.com), makers of standard and custom transformers, believes it’s imperative to understand the operation of the current sense transformer and switching transformer in order to promote their efficient use. Current Sense Transformer Current sense transformers are basically a standard transformer but the primary is placed in series with a conductor…

Nicola Tesla is one of our favorite revolutionary inventors, which is why it never ceases to shock us when we hear people ask, “who?”  It’s astounding how few people are familiar with this man’s achievements and contributions both to our industry and to the world. Earning over 700 patents over the course of his lifetime…

In theory, the power you put into the PRI side of a transformer is that available to you on the SEC side. This statement excludes losses within the core and windings but it is very useful in understanding how transformers work.     Transformers can “transform” voltage, current, and impedance. One type of transformer is known…

The Restriction of Hazardous Substances, or RoHS, is a means of controlling or limiting specific substances when manufacturing electrical and electronic equipment (often abbreviated EEE). This set of compliance laws first went into effect 7 years ago, and revisions to the original regulations have been underway for over 5 years and were finally implemented into…
