Ferroresonant Transformer Design Program

Ferroresonant Transformer Design Program (FERRO) designs a wide range of constant voltage ferroresonant transformers. FERRO designs both two-coil and three-coil (harmonically compensated) type transformers.

FERRO is used to design:

DC power supplies
Line stabilization and power conditioning
UPS output regulators
Battery chargers
Controlled ferros

Just a few many features:

Determines resonant capacitance
Accommodates any lamination shape
Accomodates C-Cores
Permits designs with round, square, and rectangular wires as well as foil. Either copper or aluminum conductors can be entered
Calculates temperature rise of primary coil and for secondary coil separately
Determines shunt air gap

Modes of operation are
- User enters core – Ferro selects wires
- User enters core proportions – Ferro determines core and wires
- User enters core and wires – Ferro determines turns and temperature
Other design considerations present in Ferro
- Capacitive reflection factors
- Harmonic current effects
- Core material permeability effects
- Input power factor
- Method of handling square wave inputs
