Toroidal transformers have many features, including:
Shape: Toroidal transformers are donut-shaped, with primary and secondary windings wrapped around the core.
Efficiency: Toroidal transformers are typically 95–99% efficient, due to their design that seals magnetic flux within the windings.
Low electromagnetic interference (EMI): Toroidal transformers have low EMI.
Compact size: Toroidal transformers are compact and lightweight, making them suitable for cramped spaces.
Quiet operation: Toroidal transformers are quiet.
Minimal heat generation: Toroidal transformers generate minimal heat.
Low magnetic field: Toroidal transformers have a magnetic field that's about one-tenth that of conventional transformers.
Core materials: Toroidal transformers can be made with a variety of core materials, including amorphous steel, silicon steel, ferrites, and powdered iron.
Mounting: Toroidal transformers can be mounted using potting and a bolt to protect the windings and allow better cooling.
Toroidal transformers are often used in power supply systems, audio equipment, control systems, power inverters, and other electronic devices.
