Abstract

809,096. Rectifying. GENERAL MOTORS CORPORATION. Jan. 2, 1957 [Jan. 18, 1956], No. 179/57. Class 38 (2). In an electric power supply a rectifier fed from a transistor oscillator is biased in its non- conductive sense on switching on by means of a condenser in order that the rectifier circuit may present a high impedance to the oscillator and so allow oscillations to start. As shown, Fig. 1, a push-pull transistor oscillator is coupled by a transformer 14 to a full-wave rectifier 63 which supplies a load 84. A battery 12 supplies the oscillator through a switch 32 and a condenser 92 is connected to the cathode of the rectifier so that immediately on closing the switch 32 the positive battery potential is applied to the cathode. This potential is applied for a period while the condenser 92 charges up through the load 84 and resistor 82 and this time period is long enough for the oscillator to start. A condenser 94 ensures that line 46 instantly acquires the positive battery potential. In a modification, Fig. 2, condenser 93, is connected between the cathode and earth via a switch 32<SP>1</SP> ganged to switch 32. On the first switching on after a period of disuse the oscillator would start since the rectifier would not conduct until the heaters are warm. During the " on " period condenser 93 is charged up. If the switches 32, 321 are opened the condenser 93 remains charged and on reclosing the switch again the charged condenser places a positive potential on the cathode thereby allowing oscillations to start. Had the circuit of condenser 32 been absent, on the second closing of the switch 32 the hot rectifier valve would have conducted, and hence the oscillations would not have started. The transistor oscillator comprises transistors 10, 10<SP>1</SP> the output circuit of 10 following the path: emitter electrode 18, collector electrode 20, winding 24, earth points 36, 34, battery 12, switch 32, and resistor 30 and the input circuit of that transistor following the path: emitter electrode 18, base electrode 22, resistor 48, resistor 30. The output and input circuits of the transistor 10<SP>1</SP> are similar. A starting resistor 62 is connected between the base electrode 22<SP>1</SP> and earth. A feedback winding 52 is connected between the two base electrodes and includes a capacitor 58 in its circuit which controls the wave shape. The Specification details the manner of operation of the oscillator.
