Abstract

847,053. Transformers; changing waveform. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. July 31, 1958 [Aug. 2, 1957], No. 24695/58. Class 38 (2). A transformer having its primary 10 (Fig. 1) and secondary 13 linking the centre limbs of two magnetic cores 1, 2, of rectangular hysteresis loop material, is provided with fine wire control windings 5 and 6 wound in opposition on the centre limbs 3, 4 of the cores. When an input of rectangular waveform is applied from source 21 (Fig. 2) to the primary, the duration of the output waves depends on the current in windings 5, 6 supplied by source 24 and hence on the voltage of source 24. The Specification states that the system may be used for the regulation of the voltage of transistor supplies by varying the duration of the signals which are to be rectified to produce the D.C. supply. The cores may be of ferrite or other material having a rectangular hysteresis loop and the transformer may be designed to match the impedance of the source 21 to that of load 23.
