Toroidal Power Transformers

Toroidal Power Transformers are made with tape wound cores. The tape wound cores provide an almost perfect magnetic circuits to minimize losses, fringing, leakage, distortion, and provide good magnetic shielding. It also decreases the magnetization force required to produce a given flux density. It is much more efficient than E-type lamination cores, but will have somewhat higher cost as the windings need to be done on the core itself, rather than on a bobbin. The tape material is made of insulated, high permeability silicon iron, with a typical thickness of 4 mils ( 0.004"). Other materials types such as 50% nickel iron alloy, Molybdenum permalloy or supermendor are also available with increased cost.

Coil Winding Specialist (CWS) has designed a series of low cost standard tape wound transformers as shown in the table "Toroidal Power Transformer - How to order ". All these transformers are designed to meet all international safety requirements ( UL, CSA, TUV, etc). Customer can order these standard transformers in small quantities for testing and prototyping.
