Low Cost Services


Fax us your transformers, chokes, coils, inductors drawings or prints or specifications and we will design them for you.

Coil Winding Specialist, Inc goal is to make the life of design engineers stress free when it comes to magnetic products, transformers designs, chokes, coils and inductors. We believe engineers these days already have too much stress, and the last thing they want to do is to worry about getting the correct transformers, chokes coils or inductors. Many engineers view magnetic as "black magic". Actually it is not if you understand the basic principles as well as we do.

Our team of magnetic and power supply design engineers, many of which have PhDs in power electronics, will do any designs for you at a low minimum cost of US$750.00. This will include complete designs plus 5 prototypes.

* Low Cost services we offer are:

  1. Power Supplies ( AC/DC, DC/DC, PFC ) design consulting. All topologies, up to 300 Khz of switching frequencies.

  2. Custom design of transformers for flyback, forward, push pull, half bridge, full bridge and resonant topologies.

  3. Custom design of common mode chokes and differential mode chokes for the above topologies

  4. Custom design of driver transformers and current sense transformers
