Custom Toroidal Transformers for OEMs

Toroidal transformers feature a ring or donut-shaped magnetic core with one or more copper windings wound through and around the core with specialized toroid winding machinery. With their unique shape, toroidal transformers offer increased efficiency and a variety of other advantages for industrial applications.

General Transformer designs and manufactures a wide range of toroidal transformers and inductors to meet your needs. Our Optimum Design practices help us work directly with you to manufacture custom transformers, and with over 45 years of design experience, we can create the best solutions for your needs. As ISO 9001-certified manufacturers, we proudly serve OEMs and manufacturers with high-quality transformers and accessories. Contact us today with any questions or to get started on your custom toroidal transformer.

Advantages of Toroids for Industrial Applications

Toroids are lighter, smaller, and more efficient than other transformers, offering many benefits to a variety of applications. The shape of the core prevents stray magnetic flux and leakage flux, resulting in less electromagnetic interference (EMI) to adjacent components. General Transformer manufactures custom transformers according to strict quality standards to ensure products of the highest caliber.

Additional benefits of toroid transformers include:

  • Smaller size and lighter weight than conventional laminated designs
  • Low form factor, flat design
  • Single bolt mounting
  • Lower losses and higher efficiency
  • Reduced audible noise
  • Inherently low magnetic flux leakage
  • Shielded designs readily produced to meet low leakage current or EMI requirements

Applications of Toroidal Power Transformers

Toroids are the best solution for compact applications that need space-saving transformers. They work well in electronic circuit applications involving computers, inverters, video, and audio. Because of their low leakage and ease of shielding, toroidal transformers are frequently used in medical devices and equipment, as well as:

Considerations for Custom Toroidal Transformer Designs

Our toroids are custom-designed for specific applications. Their available ratings depend upon your power requirements, maximum voltages, currents, and frequency. We can produce toroidal isolation transformers with ratings from 20 VA to 4 kVA for 50/60 Hz operation, autotransformers to 8 kVA, and transformers for 400 Hz operation to 20 kVA. If your project is not in those specification ranges, check out the other transformer types we manufacture.
