If you are seeking information about a Toroidal Transformer, you have reached the right place!  As your all-inclusive, on-line, resource for toroidal transformers, we offer clear, concise, information on this extremely efficient power source product! 

A good place to start with a Toroidal Transformer is to begin with its unique shape, which is that of a toroid.  A toroid is easily recognizable as a doughnut-shaped object with a torus surface.  This doughnut shape is created by a revolving circle around an axis external to the circle.  The material revolving around the circle in a doughnut shape is a coil of insulated wire (usually comprised of an iron core or similar metal). 

The toroidal transformer’s shape allows higher inductance and the ability to carry greater current than comparable solenoids of other shapes.  Because of these outstanding properties, the Toroidal Transformer is often utilized as an inductor in circuits which utilize low frequency receivers and transmitters and at the other end of the spectrum, for main power supplies.  Another design feature inherent to the toroid shape of the Toroidal Transformer is that reduced resistance is achieved due to a smaller number of windings coupled with a larger diameter.  Energy is also prevented from being absorbed by adjacent objects due to magnetic flux which is confined to the core of the Toroidal Transformer.

The superior design of a Toroidal Transformer results in a power source product which offers many advantages over other transformers utilizing standard, laminated, power.  Several powerful advantages offered by a toroidal transformer include the following:

  • The compact design of a toroidal transformer in both size and weight presents a powerful package that is easily incorporated into any power source application.

  • Low, stray, magnetic fields.

  • Quiet, efficient, operation.

We understand that the investment in a toroidal transformer is big one.  This site, presented by TEMCo, a long standing power source leader since 1968 presents education, direction, and solutions to your power source requirements.  Our desire is for you to gain the information that you need to make an informed decision on your toroidal transformer.
