Understanding Toroidal Transformers
A toroidal transformer is a type of electrical transformer with a ring-shaped (toroid) magnetic core, usually made of high-grade silicon steel or ferrite material. Its design reduces magnetic flux leakage and improves efficiency. Unlike standard laminated transformers, toroidal designs offer lower electromagnetic interference and higher power density.
In Australia, these transformers are widely used in solar inverters, LED lighting, battery chargers, and sensitive measuring instruments. Because of their compact form factor and silent operation, they are preferred in applications where space and low noise are critical.
| Parameter | Toroidal Transformer | Conventional EI Transformer |
|---|---|---|
| Core Shape | Circular (Donut) | Rectangular |
| Efficiency | High (up to 95%) | Moderate (80–90%) |
| Noise Level | Very Low | Higher |
| Size | Compact | Bulky |
| Applications | Audio, Medical, Solar | Industrial, Power Distribution |
