All toroidal transformers are similar in one way in that they all feature the toroidal or donut shape in their design. These transformers are passive electrical components and are used to transfer the power between parts of a circuit. They allow varying current as well as voltage while also providing isolation.
There are different components to all types of toroidal power transformers. The standard or off the shelf types of these transformers provide the most common features and options in design, while custom toroidal transformers can be designed to meet the specific needs of the electrical system application.
Basic Operation
The standard and custom toroidal transformers operate by utilizing two different windings, a primary and a secondary, around the core. As the current flow in on the primary winding, there is an induction of an electromotive force, which then moves to the secondary winding.
Unlike other designs of transformers, the toroidal transformer is highly compact and more efficient, with the smaller core and the tight or more widely spaced winding customized to meet the power transfer requirements.
The design of these types of transformers reduces the production of any type of heat and eliminates the risk of radiating electromotive fields. Additionally, the design also makes the toroidal transformer very resistant to exposure to electromagnetic fields from other components in the system design.
Essential Considerations in Custom Design
They are often used in medical devices and equipment due to their small size and high efficiency, but they are equally as common in computers, electronic equipment and music, and sound systems and devices.
In designing any custom toroidal transformers, there are several options to consider. The most important is the composition of the core as well as the pattern of the primary and secondary windings. The choice of custom transformers enhances the efficiency of any electrical circuit and can also increase the performance and life cycle of electronic parts and components.
