Abstract

991,951. Inverting. SIEMENS SCHUCKERTWERKE A.G. July 4, 1963 [July 7, 1962], No. 26639/63. Heading H2F. [Also in Division H3] A number of inverters supplying a common load are each driven by an oscillator, and the oscillators are maintained in synchronism by suitable interconnections. In Fig. 3, inverters 311, 312, 313 supply common bus-bars 33 from a D.C. source (not shown). Each inverter (Fig. 1) comprises a pair of thyratrons 15, 16 (semiconductor or gas) in bi-phase arrangement and a pair of transistors 12, 13 connected with a saturable transformer 11 to provide square drive pulses to the thyratrons. If the transistor base connections were made as shown at 181, 182 and 191, 192 then the transistors and transformer 11 would form an oscillator. But these connections are not made. An oscillator 321, 322, 323 in Fig. 3 comprising a transistor, resonant LC circuit and transformer with three secondary windings (Fig. 2, not shown), is associated with each inverter circuit as in Fig. 1. Two secondary windings having outputs in anti-phase are connected one at 181, 182 (Fig. 1) and the other at 191, 192. The third secondary windings of each oscillator (reference 215 in Fig. 3) are connected in parallel, so that all the oscillators keep in phase. To obtain a polyphase output, one phase from each inverter, the windings 215 are connected in series, and the oscillator outputs are then maintained at equal phase displacements.
