Toroidal Transformers Custom Built


Butler Winding designs and manufactures toroidal transformers for a variety of powerbtn_toroidal_transformer_form supply and conversion applications. A toroidal transformer is a transformer that is designed on a doughnut shaped core. Toroidal transformers offer small size, less leakage inductance and lower electromagnetic interference (EMI).

Where are Toroidal Transformers found?

Computer power supplies
Radio transmitters
Electromagnetic Interference (EMI) sensitive circuits
Any application requiring a transfer or conversion of electrical energy

Design upper limits of a toroidal transformer:

It is typical for the power rating btn_tape_wound_toroidal_transformers(expressed in VA), number of primary and secondary windings and their btn_ferrite_core_toroidal_transformersrespective voltage and current levels of a toroidal transformer to be specified as a minimum requirement.

The operating frequency should be givenbtn_power_transformers_operating_theory to allow proper core calculations and sizing.
Proper wire sizing is accomplished by specifying thebtn_toroidaltransformer_faq voltage and current levels across and passing through the toroidal transformer windings.

Toroidal TransformersToroidal transformer designs vary widely in terms of power rating, inductance, voltage level (low to high), operating frequency, size, impedance, bandwidth (frequency response), packaging, winding capacitance, and other parameters. Silicon steel and nickel iron are available as tape wound cores or laminated pieces.
