Suitable for high voltage and high current applications

For dc (rectified output) applications, ferros supply a quasi-square wave output which can reduce or even eliminate the need for filtering. For ac load applications, ferros can be designed to supply a high quality, low distortion sine wave output. Ferroresonant transformers are single phase devices, but combinations of two or three ferros can provide all of the ferros’ advantages in three phase applications.

Ferros which rely upon only their rugged copper and steel structure for regulation can easily maintain a desired output voltage within 3% despite wide variation in input voltage and/or load. Another variant, known as the controlled ferro, adds electronic control and can provide an adjustable output with regulation to better than 1%.
