Malakus The emitter of the second transistor is met, on the one hand, to the cathode of a zener diode whose anode is connected to the primary mass 8 and, secondly, to the second power supply terminal through a fifth resistor which allows biasing the emitter of the second transistor to a fixed voltage V Z between 2 and 3 volts. A third input 3 thereof is connected to the output SP of the BS power device and a fourth input axtable is connected to the positive pole P of the source of input voltage VE. Here the problem does not arise, since when the power is on, there is always a minimum load established by the scanning-line circuit. The change in this relative phase shift or this delay interval gives rise to a variation of the power supplied, and therefore, the voltage across the reservoir capacitor. The transfer of energy between the chopper circuit 10 and the cour stage 30 is conducted through the windings 21 and 22 of the transformer 20 and mulivibrateur has the effect multivibraateur charging the storage capacitor 33 which supplies, in addition to the output stage 30the preceding stages of balayge circuit not shown. Power BS asttable stabilizes the voltage VS, and at the same time the rectified voltage provided by diode D8.

Malak Note also that both halves of this circuit are emitter followers and an emitter follower courx a voltage gain of less wstable 1. In the case of a monostable multivibrator, a reactive component couples a gate output to a gate input, while supply and input sources are also coupled to the gate input. This is one of the nice things you can do with transistors — but not with ICs. The circuit illustrated in FIG. The output at terminal 18 is now relatively negative, and capacitor 24 discharges through resistors 22 and 20 as illustrated at 26 in FIG. The astable multivibrator output is substantially symmetrical, and stable with temperature. Virtually all ICs have a negative earth and do not work in a complementary version.
