Toroidal coil winding & construction techniques

The application of winding and construction techniques particular to toroidal-wound magnetic components is presented. Current trends in the design of electronic circuits has increased the opportunity to utilize toroids to satisfy an increasingly wider range of applications in everything from current sensing to power (and signal) filtering and conditioning. The principal advantages to using toroids along with some specific design criteria will be briefly reviewed. Then, specific winding and construction techniques for three specific applications, both commercial and military, will be discussed in detail
