Filed: 1973-02-20
Abstract: 1426522 Dynamo - electric machines NEWAGE ENG Ltd 15 Feb 1974 [20 Feb 1973] 8345/73 Headings H2A and H2F A circuit for providing an adjustable D.C. output from a polyphase input having at least three terminals comprises a modified bridge rectifier having a pair of diodes 16, 17 connected across first and second intermediate lines 14, 15 and having their common point connected to a first A.C. input terminal, a second diode 18 connected between a second A.C. input terminal and the first 14 of said intermediate lines and a further diode 19 connected between the third A.C. input terminal and the second 15 of said intermediate lines. A thyristor 30 in series with a D.C. load is connected across said intermediate lines 14, 15. The modified bridge rectifier provides a waveform shown in Fig. 5 having three peaks CA, CB, AB followed by a gap of 60 degrees. The thyristor 30 is turned on at an adjustable time during the three peaks and turned off by the 60 degree gap. Excitation of alternators.-The invention may be applied to excitation of the field 21 of an alternator 20 and used for automatic control of the A.C. output. The A.C. input may be derived from a three-phase pilot exciter 10 having a permanent magnet field 12. The voltage across the thyristor 30 is rectified at 45 and charges a capacitor 49 via transistor 47 until unijunction transistor 39 breaks down, triggering thyristor 30 which provides a pulse of current for the field 26 of an exciter 25, feeding the field of the main alternator 20. The voltage across one phase of the main alternator 20 is rectified at 55 and compared with a Zener diode reference 50, the resultant determining the conductivity of transistor 48 and thus the rate of charge of capacitor 49 so that the current in field 21 is regulated, thus controlling the A.C. output. The secondary exciter 25 may be omitted. Protection.-The voltage across the field 26 is monitored by a programmable unijunction transistor PUT 61 which compares it with a reference voltage across Zener diode 75. If the field voltage is excessive, PUT 61 becomes conductive, turning on a thyristor 60 which bridges the unijunction transistor 39 and thus prevents further conduction of the thyristor 30. The holding current for thyristor 60 is provided by rectifying one phase of the pilot exciter 10 so that this thyristor continues to give protection until the speed of the equipment is reduced to a low value. Modifications.-Pilot exciter 10 may be given twice the number of poles of the alternator 20 so as to minimize ripple by adjusting the relative phase of the two machines.
