How to Enhance Sound Quality with Audio Transformers

Posted by Bill Dull | October 12, 2020 | 0 Comments

At their most basic level, transformers consist of a primary and secondary winding situated around a magnetic core. Audio transformers are used to transmit sound signals from the primary to secondary winding with high accuracy and minimal distortion. Transformers are the most effective solution in many audio applications as they allow for electrical energy to be transferred from one circuit to [...]

How Does Quality Assurance Impact the Cost of a Transformer?

Posted by Bill Dull | April 7, 2020 | 0 Comments

Many customers believe that the cost of a transformer is limited to the amount that they pay upfront. At a basic level, transformer costs are determined by the time and materials used during the manufacturing process. However, the truth is that transformer costs are impacted by numerous complex factors, particularly when considering the impact on the overall system.

An Introduction to Common Mode Chokes

Posted by Bill Dull | February 28, 2020 | 0 Comments

A choke is a magnetic inductor used to block or limit unwanted high-frequency alternating current (AC) while allowing the desired lower frequency direct current (DC) to pass through. The choke acts as a filter for the noise produced by other radio signaling devices, inverters, and unshielded equipment, thereby reducing interference in electrical and electronic devices and systems.

Food and Beverage Applications for Class 2/3 Power Transformers

Posted by Bill Dull | October 3, 2019 | 0 Comments

Transformers convert alternating current (AC) from one voltage to a higher or lower voltage. Class 2 transformers are safer, more highly-rated electrical components frequently used in the food and beverage industry. Class 2 is a compliance rating which signifies that the power transformer meets safety standards that reduce the risks of fire or shock.

Autotransformer Power Transformers

Posted by Bill Dull | September 25, 2019 | 0 Comments

What is an Autotransformer?    Autotransformers feature a single winding wound onto a laminated core. They're similar to two-winding transformers, but their differences lie in the ways that the primary and secondary winding are interrelated. There are two varieties of autotransformers which may be differentiated by their construction. In the first type, the transformer relies on continuous [...]

Litz Wire vs. Copper Foil

Posted by Bill Dull | August 29, 2019 | 0 Comments

In our most recent blog, we introduced Litz wire and discussed its various uses and properties. Litz wire is a multi-strand wire used to conduct alternating current (AC) at radio frequencies. Individually insulated magnet wires are braided together in a pattern that helps reduce AC losses from skin effects and proximity effects found in high-frequency windings. In this blog, we’ll compare Litz [...]
