Peaking Transformer on a New Principle

Highly peaked voltages are obtained by connecting a linear reactor in series with a steeply saturating reactor free from magnetic joints, if the combination is excited with a sinusoidal voltage, and the saturable reactor is tapped for the peaked voltage. Similar results may also be obtained from a composite design with plenty of magnetic joints if the return magnetic circuit is arranged in two parallel branches, one branch saturable and bearing the secondary winding, and the other nonsaturating, provided that the joints are so arranged as to make the equivalent parallel path for the secondary joint-free. Such a design is shown in Fig. 2 and explained in Fig. 3. A common wrong arrangement of the joints is shown and explained in Fig. 5. Peaked voltage obtained by the design of Fig. 6 is shown in Fig. 7.
