What is a Toroidal Power Transformer?

A toroidal transformer is a type of electrical transformer with a doughnut-shaped core made of ferromagnetic material (typically silicon steel or ferrite). Unlike conventional laminated E-I core transformers, toroidal transformers are wound on a ring-shaped core, offering several advantages:

• Reduced electromagnetic interference (EMI)
• Higher efficiency (up to 95%)
• Lower core losses
• Compact size and lighter weight
• Quiet operation with less vibration

These features make toroidal power transformers ideal for applications where performance, reliability, and space are critical considerations.
