Abstract

460,449. Transformers; frequency changing; phase changing. FOSTER ENGINEERING CO., Ltd., and BAGNALL, R. I. Oct. 31, 1935, No. 30090. [Class 38 (ii)] A transformer for converting three-phase current into single-phase current of three times the frequency comprises. three annular cores 1 carrying three starconnected primary windings 2, and a common secondary winding 3 interlinking the three cores. The latter operate at saturation so that a pronounced third harmonic voltage is induced in the secondary.
