... AMVECO STANDARD SERIES INDUCTORS In addition to toroidal transformers, Amveco designs and manufactures toroidal chokes for DC-filtering and AC-circuits. As with transformers, toroidal chokes also offer significant savings in both size and weight compared to a laminated core. Presently, we manufacture chokes from 0 Ws. AMVECO has developed its own design software which allows us to design and manufacture to your specific needs. With in-house capabilities for both core-making and core-cutting, we can offer fast turn-around for both prototypes and production units ...

... CONSIDERATIONS WHEN USING TOROIDAL POWER TRANSFORMERS Substantial benefits may be derived from the use of toroids as long as thought is given to their application. The following two considerations are important. A) Shorted Turn Condition A completed path by any conductor passing through the center hole of the toroid around the outside constitutes a short circuited turn. As with any short circuit, this condition will result in high circulating currents and, more importantly, high heat ...
