Abstract

1,007,970. Converting. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. July 30, 1962 [July 28, 1961], No. 29182/62. Heading H2F. In a converting arrangement, control signals for one controlled rectifier are derived from the secondary of a transformer whose primary is connected, in series with a resistor and another rectifier of the arrangement, to an A.C. supply. Two rectifiers, 2, 2<SP>1</SP> (Fig. 4) connected in a biphase rectifying arrangement to supply a load 6, also supply through resistor 7 the primary 4 of a transformer with a current which lags the supply voltage. Therefore the voltage induced in secondary 5 has a high value when the supply voltage passes through zero, which is when the rectifiers are required to trigger To start the circuit rectifier 2 is triggered by a signal applied at terminals 8, and when the supply changes polarity at each half-cycle both rectifiers are receiving a trigger signal, and the forward biased one conducts. To stop the arrangement the secondary circuit is broken by switch 9. The resistor 7 may be in the D.C. load. A three-phase rectifier (Fig. 5, not shown) has three rectifiers with their control electrodes connected through individual resistors to a common secondary in a similar manner to that described above. Phase converting.-A single-phase to threephase converter (Fig. 6, not shown) and Fig. 7, has six controlled rectifiers and six transformers arranged so that only one rectifier conducts at a time, and the frequency of the output is onethird of that of the input. The transformer whose primary is associated with one rectifier controls a rectifier connected in the opposite sense to the supply and to a different phase of the output. More than one controlled rectifier may be connected in series, and the transformer may have more than one secondary.
