Abstract

1304279 Standby supply systems TENELUX Ltd 7 April 1970 [8 April 1969] 16336/70 Heading H2H [Also in Division F4] A standby system for a fluorescent light FL including a ballast BAL comprises an inverter INV supplied by a battery B and a semiconductor switching device CR which is rendered conductive on failure of the A.C. mains supply at terminals 8, 9 to enable the operation of the inverter, the output of which is supplied to the light and ballast. During mains operation of the light, the battery B is charged via a diode D1 and a network including resistors R2, R4 and a capacitor C1 maintains the potential at the gate 10 of the thyristor CR negative with respect to its cathode during both positive and negative half cycles of the A.C. so that the thyristor is switched off. On failure of the mains supply, the potential at the gate 10 becomes positive with respect to the cathode and the thyristor conducts to connect the battery to the feedback windings N3, N4 of the inverter transformer T1. The inverter is a self saturating type of inverter. Transistors Q1, Q2 in the inverter are alternately triggered so that a high frequency alternating voltage is induced in the secondary winding N5 of the transformer T1 and is fed to the light FL via a current limiting capacitor C2. The thyristor CR may be replaced by a transistor.
