Learning Important Terms for Toroid Core Winding

Toroidal transformers are often used in modern electronics because they are very efficient and cost effective. These small devices offer users many advantages, which include:

  • Low off-load losses
  • Flexible dimensions
  • Low magnetic field
  • Low mechanical hum
  • Small size
  • Easily mountableToroid

To get the most out of toroidal transformers, it is important that users know exactly what applications they need to be filled and what characteristics are needed from toroids. Understanding the nuances of how transformers are built and how they work will make it easier for you to construct better toroids. One of the most difficult aspects of understanding toroidal transformers is the terminology used when describing the devices. Below, we will go over some important terms.

Air core inductance– this is the inductance that is measured if cores have unity permeability while flux distributions is unaltered.

Coercive force– magnetization of field strength needs a magnetic flux density of magnetic material to be zero.

Common mode current (CMC)– signal currents that induce electrical and magnetic fields. They do not cancel one another. If a circuit has an outgoing signal and return conductor, the common mode currents are the components of total signal currents that will flow in the same way on both conductors. CMCs are the main source of EMI in a good deal of electrical devices.

Dielectric withstanding voltage (DWV)– this is the total voltage levels when dielectrics begin to break down. Once this happens conduction between isolated conductors starts.

Field strength– parameters that are characterized by the amplitude of both DC and AC field strength. This type of strength is determined by the magnitude of geometry and currents of windings.
