Toroidal Transformers and Inductors
Toroidal transformers and inductors utilize a ring-shaped magnetic core. One or more copper windings are wound through and around the core.
Advantages
- 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 are readily produced to meet low leakage current or EMI requirements
Typical Applications
Power supplies
- Battery chargers
- Inverters
- Ac filter inductors (reactors)
- Dc smoothing inductors (chokes)
- Autotransformers
- Isolation transformers
Ratings and Sizes
All of General’s products are custom designed for specific applications. Available ratings depend upon a number of factors including 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. Please do not hesitate to inquire as to your requirements.
