  • Ferroresonant Transformers
    Ferroesonant transformers are special transformers that accept variable input voltage and puts out regulated AC voltage. Ferroresonant transformers are used independently to prevent fluctuations or may be built into more functional devices such as uninterruptible power supplies. Limitations
  • Technical Article: The Ferroresonant Transformer Voltage Regulator
    The ferroresonant transformer or constant voltage transformer has a very long history having been invented in 1938 by Joseph Sola and continuing to sell tens of thousands of units per year. The ferro of today has had some minor improvements but remains fundamentally unchanged from the original
