Abstract

1472465 Standby systems; battery chargers PLESSEY CO Ltd 11 April 1975 [16 April 1974] 16659/74 Heading H2H Standby supply and battery charging apparatus comprises transistors arranged to be connected to a battery and a transformer connected to the transistors and arranged to be connected to the mains, the apparatus being such that when a connection is made to the battery the transistors operate together with the transformer in a transformer cotrolled pushpull mode to convert the D.C. voltage of the battery into A.C. voltage for a load, and when a connection is made to the mains then mains voltage is fed to the load and the transformer which then conducts A.C. voltage to the transistors which rectify this for transmission to the battery for charging. As shown, when the mains is not connected across terminals 1, 2, or it has failed, all switches are in the positions indicated and switch 9 is closed. D.C. from the battery connected between terminals 4, 5 is passed by transistors 18, 20 in opposite directions in the 2 halves of centre-tapped primary winding A of transformer T1 to generate A.C. in the secondary B which is passed to the load connected across terminals 1, 3. If the mains is present relays 8, 10 cause contacts 28 and 12 to close and contacts 14, 16, 22 to change over. The base-emitter junctions of transistors 18, 20 are both shorted and the base-collector junctions act as diodes to full-wave rectify the A.C. induced in winding A of transformer T1 to thereby charge the battery. Voltage limiting Zener diodes may be connected across the winding A.
