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. Because of their unique design, toroidal transformers offer increased efficiency and less electromagnetic interference (EMI) than stacked, or EI transformers.
General Transformer Corporation designs and manufactures a wide range of toroidal transformers and inductors for OEMs and manufacturers across virtually any industry. Our toroidal transformers feature a smaller design, lower noise output and higher efficiency than standard laminated transformers. GTC’s engineers have 45 years of experience designing transformers. Our toroidal transformers are an ideal choice for low current and low voltage applications. Our Optimum Design practices help us work directly with you to manufacture ISO 9001-certified custom transformers to meet your needs.

Toroidal Power Transformer Benefits
- Compact, Lightweight Design: Toroidal transformers utilize a smaller size and lighter weight than conventional laminated designs. This makes toroidal transformers ideal for mobile applications.
- Lower EMI For Higher Efficiency: GTC’s shielded designs largely reduce magnetic flux leakage, and can be readily produced to meet low leakage current or EMI requirements. They feature lower losses and operate at higher efficiency.
- Low Stray Field & Noise: The field generated by magnetization is lower in a toroidal transformer for lower noise and higher performance.
- Cost-Effective: Toroidal transformers require fewer materials to construct and provide a more economical output than standard transformers.
- Easy to Install: General Transformer Corporation toroidal transformers utilize single mount bolting. They feature a low form factor, flat design.

Applications of Toroidal Power Transformers
Toroids are the best solution for compact applications that need space-saving transformers. Because of their low leakage and ease of shielding, toroidal transformers are frequently used in medical devices and equipment. These transformers also feature high reliability for transformer products for industrial and manufacturing applications. They work well in electronic circuit applications involving computers, inverters, video, and audio. Toroidal Transformers are designed to withstand harsh environments for oil and gas, renewable energy uses and other demanding applications.

What is The Difference Between Toroidal Transformers & Normal Transformers?
The primary difference between toroidal transformers and regular stacked lamination transformers is their physical structure. In toroidal transformers, the primary and secondary are wound over each other. This creates a toroid-shaped core that is constructed from a continuous loop of magnetic metal. The shape of the core prevents stray magnetic flux and leakage flux, resulting in less electromagnetic interference (EMI) to adjacent components. Toroidal transformers are therefore able to offer a lighter, smaller, and more efficient alternative to other transformers.
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.
General Transformer manufactures custom transformers according to strict quality standards to ensure products of the highest caliber.
