Abstract

A controllable transformer has at least one primary coil (7, 7a, 7b, 7c), one secondary coil (8, 8a) and one control coil (9) each located on a respective core section, in which the alternating voltage from the output of the secondary coil is controlled by the control coil (9) which is energised by direct current. The axes (10, 11, 12) of the windings of the secondary coils (8, 8a) and the control coil (9), and conveniently also of the primary coils 7, 7a, 7b, 7c) are at least approximately parallel. <IMAGE>
