Abstract: 956,259. Transistor oscillator circuits. GENERAL ELECTRICAL CO. Ltd., and P. BURROWS. Dec. 4, 1962 [Sept. 4, 1961; Aug. 24, 1962], Nos. 31722/61 and 32623/62. Heading H3T. A generator overload protection circuit comprises means whereby the impedance presented to the generator may be maintained sufficiently high to prevent overloading, at least for a limited period, when the load impedance to which power is supplied is reduced to a value which, if presented directly to the generator, would cause overloading. An overload protection circuit for a saturable transformer transistor D.C.-A.C. inverter 1, Fig. 1, comprises a relay 12 connected in series with a Zener diode 11 and a silicon rectifier 9 across the output winding 3 of the inverter transformer. Under normal conditions relay 12 is operative, and the changeover contacts 6 connect the output terminal 8, 5 across the whole of the output winding 3. If under fault conditions the load impedance across terminals 5, 8 decreases, relay 12 releases and the load is connected only across a small part of the output winding, thus presenting a higher impedance to the inverter. After restoration of normal conditions reoperation of the relay is delayed until capacitor 13 becomes charged. The circuit may be used for supplying a filament lamp, the output across the tapping being sufficient to heat the filament to its normal working impedance. In a second embodiment, Fig. 2, a D.C.-D.C. converter comprises an oscillator 14 similar to that of Fig. 1 followed by a rectifier 16. Under normal conditions relay 23 is held operative, shorting out resistor 21 and inserting resistor 22 in series with the energizing coil. A fault condition causes the relay to release shorting resistor 22 and inserting resistor 21 in series with the load. The impedance then presented being such as to allow the generator to continue working to supply other loads which may be connected across terminals 17, and also to allow sufficient current to flow through the load to operate a breaker.
