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
Notable 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
- Data is entered by source files
- 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
