A device for stabilizing the current has a core whose ratio of the sectional area of the second leg (S2) to the sectional area of the first leg (SI) is within the range of 0.6-0.95 and a compensating winding wound around the first leg of the core, while producing no saturation of the magnetic flux. It is possible to save at least 30% or usually 50-70%, or more preferably 80-90% of the consuming power when comparing with the prior art for limiting the current. |
