Abstract

1435331 Converting LEGRAND SA 2 July 1973 [3 July 1972] 30873/73 Heading H2F A low voltage D.C. is obtained from a switching device 17 in an A.C. circuit by connecting a constant voltage device 26 in series with the switching device 17 so as to develop a first voltage when the switching device 17 is conductive and including a further circuit connected across the switching device 17 for providing a second voltage when the switching device 17 is non-conductive, the low D.C. voltage being derived from the first and second voltages. The invention is applicable to deriving a low voltage D.C. for use in the control circuit 16 of a triac 17 arranged to switch a lighting load 14 from an A.C. source 12, e.g. by means of a photoconductor (not shown) connected to the gate 25. When the triac 17 is non-conductive the supply voltage 12 is reduced by capacitor 22 and resistor 23 and is rectified by diode 27, smoothed by capacitor 29 and regulated by Zener diode 30. When the triac 17 is conductive, the inverse diodes 26 will provide a low stabilized A.C. which is stepped up by transformer 20, rectified at 28 and fed to the smoothing and control circuit 29, 16. In Fig. 3 (not shown) diodes 24 and 28 are omitted and junction A is connected to point M. In Fig. 5 (not shown) diodes 26 are connected on the source side of the triac 17 and feed the primary of a doublewound transformer having a centretapped bi-phase halfwave pair of rectifiers for use when the triac 17 is conductive and having a circuit similar to that shown in Fig. 2 for use when the triac is non-conductive. Modifications.-The triac 17 may be replaced by an electromagnetic relay or a thyristor. Diodes 26 may be replaced by thyristors or triacs. The transformer 20 may be replaced by a voltage multiplier.
