A toroidal transformer is a type of transformer that utilizes a toroidal (doughnut-shaped) core made of ferromagnetic material, typically iron powder or laminated iron. The primary and secondary windings are wound around the core, providing a closed magnetic circuit. This design offers several advantages over other types of transformers with different core shapes, such as E-I or C cores. Key features and benefits of toroidal transformers:

1. Efficiency: Toroidal transformers are known for their high efficiency due to the closed magnetic circuit, which reduces magnetic flux leakage. This design results in lower electromagnetic interference (EMI) and better overall performance.

2. Compact Size: The toroidal shape allows for a more compact and space-efficient design compared to transformers with other core shapes. This is advantageous in applications where space is limited.

3. Reduced Stray Magnetic Fields: Toroidal transformers generate less stray magnetic fields compared to transformers with other core shapes. This can be beneficial in applications where minimizing electromagnetic interference is critical.

4. Low Noise: Due to their design and reduced stray magnetic fields, toroidal transformers tend to operate more quietly than transformers with other core shapes.

5. High Power Density: Toroidal transformers can handle high power levels relative to their size. This is particularly useful in applications where a compact design is required without sacrificing power-handling capabilities.

6. Ease of Mounting: Toroidal transformers often have a centralized mounting hole, making them easy to install and secure in various applications.

7. High Inrush Current Capability: Toroidal transformers typically have a higher inrush current capability, which can be important in certain applications where there is a brief surge in current during startup.

Applications of toroidal transformers include audio equipment, power supplies, medical devices, lighting systems, and various electronic devices where size, efficiency, and low electromagnetic interference are critical factors.
