Abstract

1,214,313. Automatic voltage control. MULLARD Ltd. June 18, 1968 [July 12, 1967], No.32017/67. Headings G3R and G3X. [Also in Divisions H1 and H2] A D.C. power supply (e.g. for the line time base in a television receiver) comprises an A. C. supply, half-wave rectified by a thyristor T1, the conduction angle of which is delayed by an R. C. network R7, C1 until a bi-directional semi-conductor breakdown device D1 breaks down, the charging of C1 being controlled by a shunt transistor T2 in dependence on the output voltage. As described, the A.C. supply A, B is rectified by thyristor T1 and smoothed by L1, R11, C3, C4. The conduction angle of T1 is arranged so that the output voltage is reduced to 150V; this is achieved by charging C1 during each half cycle until a diac D1 breaks down when thyristor T1 is triggered, and supplies power to the D.C. load. A feedback circuit via R5 ensures that the combined A. C. and D.C. bias on transistor T2 provides stabilization of the output voltage by variation of the charging time of C1. Zener diode D2 minimizes the temperature effect of transistor T2, A double -emitter transistor (see Division H1) may be employed instead of components T2 and D2.
