Abstract

936,625. Transistor oscillator circuits. SVENSKA A B. GASACCUMULATOR. Feb. 9, 1960 [Feb. 16, 1959], No. 4528/60. Class 40 (6). In a push-pull transistor invertor having regenerative feedback proportional to the load current, an inductance is connected across the points of application of feedback, the B/H characteristic of the inductance being so related to the Vb/Ib of the transistors that the frequency is substantially independent of supply voltage or load current. As shown in Fig. 8, regenerative feedback proportional to the current in the load 8 is applied via the frequency controlling transformer 14. The knee of the B/H characteristic lies at a value of magnetizing current corresponding to the base current at the knee of the Vb/Ib characteristic of the transistors and the slope of the B/H characteristic above the knee is equal to that of the Vb/Ib characteristic. The feedback current is five times that required to bottom the transistors. In Fig. 10, an auto-transformer 18 forms the frequency-controlling inductance, diodes 11, 12 respectively completing the base circuits for transistors 2, 1. In Fig. 11 (not shown), two separate transformers form the frequency-controlling inductance. Fig. 9 (not shown), relates to an arrangement wherein the transistors are directly connected to a centretapped load.
