Abstract

398,798. Converting. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Dec. 18, 1931, No. 35131. Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 25, 1931]. [Class 38 (ii).] Relates to a polyphase inverter system such as that shown in the Figure, in which a plurality of single phase grid-controlled valves 21<1>, 21<11>, 22<1>, 22<11>, 23<1>, 23<11> are associated with the primary winding of a transformer 4 having a star-connected secondary feeding the load circuit 3, and consists in omitting the neutral connection on the secondary side in order to cause magnetic linking of the several single phase rectifiers. When applied to feeding an induction motor, the windings of the latter may replace the transformer windings.
