Abstract
969,106. Converting. SIEMENS-SCHUCKERTWERKE A.G. Aug. 3, 1962 [Aug. 3, 1961; June 22, 1962], No. 30078/62. Heading H2F. [Also in Division H3] Two semi-conductor devices having thyratrons like characteristics are connected in parallel and fired by firing a third semi-conductor thyratron. In Fig. 2 the semi-conductor thyratrons 21-24 connected in parallel to a load 27 are fired by triggering a semi-conductor driver thyratron 20. If one of the parallel thyratrons fires more quickly than the other the supply to driver thyratron 20 would be shortcircuited but to provide sufficient energy to fire the remaining one an inductor is connected in series with the driver thyratron. Where the driver is connected directly to supply terminal 26 a capacitor can be connected in place of the inductor (in parallel with a discharge resistance) to limit the firing current to a narrow pulse. Fig. 3 shows a full-wave rectifier circuit using parallel semi-conductor thyratrons and separate driver thyratrons. The circuit is also usable as an inverter if a D.C. supply is connected in the reverse sense to that indicated to terminals 361 and 362 and the driver thyratrons are reversed. Three-phase rectifier systems are illustrated in Figs. 4 and 5 (not shown). Fig. 1 shows a pulse generator for connection to the driver thyratrons 20 (Fig. 2) and which produces an output pulse having a position in a reference A.C. wave dependent on a control voltage. The control voltage and the reference A.C. are applied between terminals E and A to a transistor which is normally conducting. During the course of the input wave the transistor becomes non-conducting and later on conducting again. When this latter occurs a rapid build-up of current is produced in the transistor due to regeneration between windings 121 and 124 and a current pulse flows to charge capacitor 162. This produces output pulses at terminals 181 and 191 which can be connected to the inputs of different driver thyratrons.
