Toroidal Transformer


Definition of Toroidal Transformer

A toroidal transformer is a type of electrical transformer that features a doughnut-shaped core made of a ferromagnetic material, typically iron powder or ferrite.

It’s designed to step up or step down voltage in electrical circuits by electromagnetic induction.

Toroidal transformers are known for:

  • High efficiency
  • Low operating temperature
  • Low noise
  • Compact size
  • Increased resistance to external magnetic fields

Their compact size and superior electromagnetic interference (EMI) suppression make them ideal for all sorts of applications, from audio equipment to stepping down high voltage to low voltage for LEDs.

If, for example, you have several 10–30 DC volt Mantis Dock Light Single lights, you can’t connect it directly to the high voltage 110 volt AC mains. You may use a toroidal transformer in tandem with LED drivers as they’ll give you higher output wattage and constant voltage, respectively.

Example of Toroidal Transformer in a Sentence

"The high efficiency and low magnetic leakage of a toroidal transformer make it a popular choice for use in power supplies for electronic device"
