Ferroresonant transformers, also known as constant voltage transformers (CVTs) or ferros, provide a range of benefits to any application. Ferros offer current limiting, protect sensitive loads from disturbances, and are designed with a low-pass filter to suppress transient and surge voltages. They can also “ride through” brief power outages of one-half cycle without losing output voltage. Other benefits of ferroresonant transformers include:Fixed output voltage or adjustable output voltage, depending on design

  • Rugged and reliable operations
  • High levels of isolation
  • Quasi-square wave output waveform reduces filtering requirements for DC applications
  • Low distortion sine wave output available for AC load applications
  • Ratings from 100 VA to 10kVA for 50/60 Hz operation
  • Fully customizable designs to fit your requirements
  • Ability to be used in combinations of two or three for three-phase applications
  • And many others!

We Manufacture Ferroresonant Transformers to Match Your Specifications

GTC’s vast range of proven ferroresonant designs allows us to provide maximum power in a smaller package. Our transformers are custom-built for specific applications, from simple constructions to complex configurations. Available ratings depend upon several factors:

  • Power requirements
  • Maximum voltages
  • Currents
  • Frequency

Based on your requirements, our conventional ferros have a fixed output voltage and can readily provide line and load regulation within 3%. Our controlled ferros can feature an adjustable output voltage and, depending on the control circuitry, line and load regulation better than 1%.

Custom Ferroresonant Transformers for OEMs

General Transformer works with several industry-leading OEMs, delivering a continual supply of high-quality custom ferros. If your circuit incorporates an existing ferroresonant transformer, we invite you to improve its performance, efficiency, and cost with one of our custom redesigns. Our engineering team is prepared to meet the demands of any OEM across markets, including but not limited to:

  • Motor control manufacturers
  • Industrial equipment manufacturers
  • Semiconductor manufacturers
