Figs. 1 and 2 show conventional methods of interconnecting the main core and the shunt core of a controlled transformer with a "bottleneck" structure. The configuration in Fig. 1 shows the bottleneck laminations running parallel to the laminations of the main and the shunt cores. The configuration in Fig. 2 shows the bottleneck laminations running perpendicular to the laminations forming the main and shunt core. With either configuration the flux 12 emanating from the main core and passing through the bottleneck to the shunt core flows perpendicular to the laminations. This result is undesirable in that unwanted eddy currents are experienced in the structure, and an inordinate reluctance is encountered due to the effects of the series of air gaps between the laminations.
