Abstract

940,597. Transistor oscillators. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Nov. 17, 1961 [Nov. 25, 1960], No. 41239/61. Addition to 931,322. Heading H3T. [Also in Division H2] A main inverter controlled by a self-excited inverter whose D.C. circuit includes a controlled semi-conductor device, such as a transistor p3, which is made conducting by a rectified portion of the main inverter output according to the parent Specification has an additional circuit including capacitor k4 and at least one amplifying member, such as p8, p9, p10, arranged so that the first mentioned controlled semi-conductor device is made to conduct briefly when the D.C. supply 20, 21 is switched on, so as to make unnecessary the starting push-button of the main patent. The main inverter comprises parallel operated transistors p4, p5 and p6, p7 and the centre-tapped primary winding of transformer t2 whose secondary supplies load circuits 3, 4, 5, 6, 7, such as fluorescent lamp p23, through an antiresonant circuit having capacitor k1 and inductances d1, d2 to improve the output waveform and through thermistor r21 which damps the starting current through the compensating capacitors such as k7. The self-excited inverter comprises transistors p1 and p2, and the centre-tapped primary of transformer t1 whose secondaries supply the control signals for the main inverter. Both inverters are supplied from a common D.C. source, the self-excited inverter being supplied through transistor p3. The frequency is determined by the ganged variable resistors r22, r23, and variable resistor r24, r26, r27 permit the half-waves to be made symmetrical. The network of elements N6, k5, r8 and the network N5, k3, r9, whose components are not necessarily of the same values, serve to reduce excess voltages at the transistors pl and p2. When transistor p9 is conducting p10 is blocked, and consequently transistor p3 conducts. The transformer t3 and bridge rectifier make transistor p9 conduct when there is a voltage between the output conductors 1, 2. Transistor p8 normally conducts and therefore tends to block transistor p9 and hence transistor p3, but when the inverter is first switched on the charging of capacitor k4 causes blocking of transistors p8, and hence transistors p9 and p3 become conducting, so starting the inverter.
