Abstract

1516921 Standby supply systems; converters INTERNATIONAL STANDARD ELECTRIC CORP 28 Jan 1976 [6 Feb 1975] 03278/76 Headings H2H and H2F A standby supply system for supplying D.C. to a load 3 comprises a battery 2, a rectifier circuit 1 supplied from an A.C. source 9, and a D.C. to A.C. converter 4 controlled by the load current and/or the load voltage, the output of the converter being fed back to the A.C. source or to the rectifier circuit in dependence on the state of charge of the battery and the converter being controlled by the load current and/or the load voltage so that the load receives the correct supply voltage independent of the instantaneous state of the battery. When the mains supply is present, the rectifier circuit 1, which includes thyristors T 1 , T 2 controlled by a circuit 15, charges the battery 2 and supplies D.C. to the load via a smoothing circuit 5, 6. The converter 4, which includes thyristors TA, TB controlled by a circuit 8 in dependence on the load voltage, feeds back to the supply 9 any voltage in excess of that required by the load. If the mains supply fails, at least one of the thyristors TA, TB is held conductive so that the battery supplies power to the load. A system for use with a three phase supply is also described.
