Abstract
1346406 Supply systems for gas discharge lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 Sept 1972 [17 Sept 1971] 42753/72 Heading H2H [Also in Divisions H3-H5] A D.C. to A.C. converter provided with at least one transistor whose emitter is connected at least through a resistor to the base, and furthermore provided with a transformer having primary, secondary and coupling windings, in which at least part of the primary winding forms part of the main electrode circuit of the transistor, arranged across two input terminals of the converter, and in which a coupling capacitor is connected between the coupling winding of the transformer and the connection between the resistor and the base of the transistor, is characterized in that the connection between the emitter and the resistor includes an auxiliary direct voltage source of a polarity which would render the transistor conductive if the resistor were short-circuited. In a first embodiment, the collectors of transistors 5, 7, Fig. 1, are connected to either end of the primary winding of transformer 4 which is of high leakage inductance the centre-tap is connected via terminals 1, 2 of a source of supply and an inductor 6 to the emitters of the transistors. Capacitor 21 is connected across the primary, while the secondary feeds discharge lamps 10, 11. Coupling winding 8 is connected at one end to the base of transistor 5, and at the other via capacitor 20 to the base of transistor 7: it also feeds via capacitors 19, 19
