An Introduction to Toroidal Power Transformer

As you might already know, transformers are devices that transfer power between two parts of an electrical circuit by creating an isolation with varying current and voltage. They are an integral part for almost all electrical applications. Power transformers, are used when high-efficiency power transfer is needed. Depending on the specific application, devices may operate …

Autotransformer vs Isolation Transformer

An isolation transformer is an electrical transformer with a primary and secondary coil winding. These windings are separated by insulation. This insulation limits the risk of electrocution when the active parts and earth are touched simultaneously. An autotransformer is an electrical transformer with only one winding. The term “auto” refers to a single coil acting …

What are balun transformers?

In the world of electronics, it’s common to hear about two varieties of lines—balanced and unbalanced. Balanced lines have two conductors, which feature equal currents running in opposite directions. An example of balanced lines is twisted pair cables. On the other hand, unbalanced lines feature just one conductor and a ground, like a coaxial cable. …

Incoming Inspection Testing on Soft Ferrite Cores

Many a times power electronics engineers find magnetics design as a complex process and when it comes to incoming inspection of ferrites – many have very basic knowledge and lot of misconceptions. Here’s a good application note on the same. Research paper originally appearing on MH&W International Corp. NJ, USA.
