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…

HF Series Power Chokes Have High Flux Cores to Handle Very High DC Bias Current. Windham NH, MAY 22 — CET Technology (www.CETTechnology.com), makers of standard and custom magnetic devices, including toroidal inductors, step down transformers and many other devices, also make a complete line of toroidal inductor power chokes. Made with high flux cores and…

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 general, the primary and secondary windings in a transformer possess the same amount of inductance. This means that there is equal voltage and current levels in both circuits. There are circumstances, however, when voltages don’t match. For example, imagine that your electricity runs at 220 volts, but you have a 120V device, which is…

The impedance of an inductor is proportional to its inductance and the frequency of the signal passing through it.  Inductors, therefore, can act like low-pass filters, that is they allow low-frequency signals to pass through them, while they block higher frequency signals.  A common mode choke is a special type of filter with two inductor…

Whether you need standard, off-the-shelf power supplies or a custom-designed unit for a specialty application, there are some key pieces of information you will want to consider as you make your switching power supply choice. At CET Technology, we offer both standard and custom power supplies and are happy to help you find the one that…

Vulf Ozechov passed away unexpectedly on 9 June 2013 at the age of 78 at his home in Skokie, IL.  Vulf designed transformers, inductors, motors, and electromechanical equipment for more than half a century at companies and organizations on three continents. Ozechov was born on 22 May 1935 in Lazdiy, Lithuania.  At the age of…

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…

Who Invented the Inductor? The use of electrical transformers and inductors in the electrical realm is such common practice that it’s hard to imagine a world without these devices. When the property of inductance was discovered in the 1830s by Joseph Henry and Michael Faraday (separately and on different continents), technology was revolutionized. Inductance was…
