Abstract

1,109,212. Alternative power supply systems. BORG-WARNER CORPORATION. 1 March, 1966, No. 8900/66. Heading H2H. An electric power supply system wherein an output circuit 12 is normally supplied from an A.C. input circuit 11 by way of a rectifier 10 has means provided whereby should a transient failure of the A.C. supply occur the output circuit is supplied from a battery 13 but that should the failure persist for longer than a predetermined time (e.g. 2 seconds) the supply from the battery is interrupted in order to protect the battery. When a failure of the A.C. supply occurs a switch 29, which is normally a thyristor, closes whereupon a circuit to the output circuit 12 is completed from the battery 13 by way of a circuit device 17. The signal developed in the device 17 is applied to an amplfier 18 to close a switch 34, which may be a further thyristor. Relays 20, 21 are then energized from the output circuit 12 by way of contact 28 of a relay 26 in a voltage sensing means 16 and the switch 34. Energization of relay 20 closes contact 24 whereupon the output circuit 12 is supplied directly from the battery 13. Should the failure of the A.C. supply persist for longer than the predetermined time, the energization of the relay 21 closes a contact 31 which is given a delay equal to that time. A relay 22 is then energized to open contact 33 then interrupting the supply from the battery to the output circuit. Should, however, the A.C. supply be restored before contact 31 closes, the relay 26 is energized opening contact 28 and de-energizing relays 20, 21. The system then is returned to normal with the output circuit 12 supplied from the A.C. supply by way of the rectifier 10.
