What Is a Toroidal Power Transformer?

Posted by Bill Dull on August 14, 2018

Transformers are devices used to transfer power between two parts of an electrical circuit, creating isolation while varying current and voltage. Transformers serve as integral components in most electrical systems.

Exploring Current Sense Transformers

Posted by Bill Dull on June 11, 2018

Commonly employed in high-current circuits, current sense transformers (CSTs) are a type of instrument transformer used to measure current values in a conductor.

In current transformers (CTs), the primary has very few windings and is connected in series with the conductor carrying the current to be measured. The secondary contains a number of windings that are wound around a secondary ferromagnetic core. Current transformers are sometimes referred to as “series transformers” because the primary winding — which always has very few turns — is in series with the current-carrying conductor supplying the load.

Understanding the Maximum Power Theorem

Posted by Bill Dull on April 10, 2018

The maximum power theorem, better known as the maximum power transfer theorem, is an essential tool for ensuring successful system design. Put simply, this theorem states that the maximum power that can be transferred from source to load is 50%, which occurs when source impedance is exactly matched to load impedance. The theorem is not as simple as it seems at first glance, however, and can be easily misunderstood.

An Introduction to Impedance Matching Transformers

Posted by Bill Dull on March 27, 2018

In order to keep your equipment running smoothly, avoid unplanned downtime, and properly maintain equipment, you need to first ensure that your electrical systems are in check and free of common problems. Electrical impedance, in particular, can hinder the performance of your equipment and cause major, system wide issues.

Differential Mode vs. Common Mode Chokes

Posted by Bill Dull on November 20, 2017

Noise and other electromagnetic interference (EMI) can pass through electronic equipment as a result of coupling, conductively, via the equipment wires. When this noise occurs on a single line, it adds to the carried signal and is referred to as differential mode noise.
