Results are given for a small laboratory model of a treble-tripler sat
urated reactor. Computed and experimental values are in reasonable agr
eement and illustrate the large change of current for a small voltage
change together with low harmonic generation. Unbalanced voltage energ
isation produces a corresponding negative-phase sequence current in th
e supply with a significant third harmonic component. (C) 1997 Elsevie
