What Is An Audio Transformer?

Audio transformers are electronic devices that transmit frequencies within the audio band. They are used in audio amplifier circuits to:

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.

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 winding and taps are brought out at convenient points based on the desired secondary voltage.
• In the other style of autotransformer, two or more distinct coils are electrically connected and form a continuous winding.

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 wire and copper foil—a thin metal sheet made from soft copper—and discuss their applications in transformer design.

Our engineering team frequently receives questions about whether we use Litz wire in our designs. We decided to focus this blog on educating our clients on this subject and explain why Litz wire is so ideal for certain applications and industries. Using Litz wire is associated with a number of benefits, including:

Transformers are electrical devices with the capacity to change the voltage level of an alternating current (AC) in a circuit. They function only with AC circuits, not with direct current (DC) circuits. The basic components of a transformer are two separate coils of wire wound around a single core. The coil connected to the incoming or voltage source is the primary coil, the coil connected to outgoing or voltage output is the secondary coil, and the core is an electromagnetic device that impedes (limits) or amplifies (increases) voltage flow according to output requirements. 

A more in-depth investigation into how transformers work, their various types, and their common applications helps provide a greater understanding of the critical function they serve in providing usable power to operate computers, appliances, lighting fixtures, and a wide range of other electrical and electronic devices.

Complex electronics sometimes create stray electromagnetic fields, which can interfere with the performance of other electronics. This problem is especially prevalent in confined spaces like hospital rooms and surgery floors, and interference can be even more dangerous when it applies to delicate tools such as health monitoring equipment.

The medical industry’s multifaceted, complex, and ever-changing regulatory landscape means that designing medical equipment requires the utmost care and efficiency. This especially applies to electrical applications since faulty components could negatively affect both patients and operating personnel. We at Triad Magnetics know the importance of getting medical equipment right, and we ensure that all our products meet and exceed the strictest safety regulations. 

How are magnetics involved in this week’s football game?

This Sunday, as Los Angeles prepares to take on New England on football’s greatest stage, millions of people from across the globe will tune in to watch the action. But without the help of wound magnetic components, the Big Game would not even be possible!

Triad Magnetics is pleased to announce that Jim Tracy has marked sixty years with the power supply and magnetics company. Jim, or JT as he is known to colleagues, joined Triad on January 19, 1959, when the emerging transformer company was primarily a military contractor based in Venice, CA. In his six decades with Triad, JT has been a vital part of the company’s sales growth and has seen incredible technological change and innovation.
