Abstract: 1384175 Frequency changing E I BERK- -OVICH J P GRIGORIEV J M INKOV I I PRESMANN and V P FEOKTISTOV 1 June 1972 25571/72 Heading H2F In a frequency changer comprising two groups of anti-parallel thyristors 5, 6, 7; 8, 9, 10, simultaneous conduction of the two groups is prevented by monitoring the anode/cathode voltages of each thyristor by means of a first winding 15 of a respective transformer 13, a second winding 14 of each transformer being in series with the trigger pulses supplied to the gate of the respective thyristor, each transformer 13 having a centre-tapped winding 16 the outer ends of which feed the two inputs of a respective bi-stable trigger circuit 23. As described, the frequency changer is supplied with three-phase supply A, B, C and produces a three-phase output of reduced frequency for load 4 for use, e.g. in ships, trains or aircraft or for stirring molten metal. Each thyristor is turned on by pulses at appropriate times from sources 11 or 12, the resulting pulse produced in winding 16 setting the respective bi-stable trigger circuit 23 to "0". When the anode/ cathode voltage of the thyristor becomes reversed (thus turning off the thyristor), a current pulse is passed through winding 15 the resulting pulse in winding 16 setting the respective bi-stable trigger circuit 23 to "1". The outputs of the three bi-stable trigger circuits 23 associated with group 5, 6, 7 are fed to an AND circuit 25 whilst those of the bi-stable trigger circuits 23 associated with group 8, 9, 10 are fed to a further AND circuit 26; the outputs of circuits 25, 26 being fed to a further AND circuit 27. The outputs of circuit 25 ... 27 are used to prevent simultaneous conduction of the two groups of thyristors.
