Switched Mode Power Supply

By sps | Electrical Technology, Education, Power Supplies | Comments are Closed | 28 October, 2019 | 0

A switched mode power supply (SMPS) is a more modern and efficient take on the older power supplies known as linear supplies.   LINEAR SUPPLIES Linear supplies would often take in line voltage, transform this via a low-frequency silicon steel core transformer to a lower voltage. Then through rectification using diodes, and filtering using capacitors,…

The Basics of Common Mode Choke Windings

By Michelle Farnum | Electrical Technology, Inductors | Comments are Closed | 3 December, 2016 | 0

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 inductor is a special type of filter with two…

Understanding Why Step-Down Transformers Are Used

By Michelle Farnum | Electrical Technology, Education, Transformers | Comments are Closed | 27 February, 2014 | 0

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…

What to Consider When Purchasing a Power Supply

By Michelle Farnum | Electrical Technology, Education, Power Supplies | Comments are Closed | 23 October, 2013 | 0

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…

Restructured Compliance Regulations with RoHS2

By Michelle Farnum | News & Announcements, ROHS, Electrical Technology | Comments are Closed | 21 August, 2013 | 0

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…

History of Transformers and Inductors

By Michelle Farnum | Electrical Technology, Education, Transformers, Inductors | Comments are Closed | 28 July, 2013 | 1

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…

Custom Chokes

Here at CET, we do custom transformer and inductor solutions every day. One such part was a high current custom choke desired by a customer of ours. The design of this part actually went through a couple of iterations. Initially, we designed for performance keeping cost in mind. Our solution was a performance success, but the…

 

What is an Inductor?

What is an inductor, its purpose, and how does it work? Inductors are an electrical component made essentially of a coil of wire, often wound around a magnetic core. From our experts, here are some facts to help you better understand this technology.   What is the Purpose of an Inductor? The purpose of inductors are that…
