Abstract

824,211. Frequency changing. BRITISH THOMSON-HOUSTON CO. Ltd. March 25, 1958 [March 25,1957], No. 9718/57. Class 38 (2). Polyphase, e.g. two-phase, current of low frequency is obtained at terminals 01, 02, 03 from apparatus comprising an induction regulator 1 having a rotor winding R supplied with singlephase current, a stator with polyphase, e.g. twophase windings XO, YO, rectifiers 2, 3 in the output of the rotor windings and reversing switches 6, 7 which invert the D.C. outputs of the rectifiers at the frequency at which the D.C. amplitude varies as a result of the rotation of the induction regulator. Switches 6, 7 are operated by cams 4, 5 driven with the induction regulator.
