Description

Tra 13 and the adjustable resistor connected to it. 14. With increasing (decreasing) of the parameters are adjustable; the resistor 14, which corresponds to an increase (decrease) in the voltage on the regulating element 6, the output voltage of the stabilizer, which is applied to the converter, decreases (increases) to such a value that the tension falling on the regulating element 6 is restored to the specified value . Thus, the voltage ita is stabilized by the regulating element 6 of the output stabilizer, which performs the basic stabilization of the output voltage.

The operation of the intermediate stage is as follows. The voltage (or part of it) falling on the regulating element 6 is iodized to the additional measuring element 9, where it is compared with a stable on-voltage. The difference of these voltages (supplied to the donor measuring element and the reference voltage) controls the operation of the control signal generator //. The pulses produced by the controlled oscillator // signals are removed from the output winding of this heater and are exhausted with a rectifier rectifier 12, after which the tip capacitor of the filter 13 receives a constant pressure. With an increase in the voltage on the regulating element 6, the adjustable signal generator 11 starts to generate pulses or the amplitude and frequency of these pulses increases. Moreover, in this mode, the accumulative capacitor of the filter 13 is recharged by the idle pulse pulse and recharged faster than it can discharge through the adjustable resistor 74, and the evaporation of the filter capacitor 13 of the filter 13 grows. A decrease in the voltage on the regulating element 6 leads to a decrease in the amplitude and frequency of the pulses, or else the controlled signal generator 11 stops generating pulses altogether. In this mode, the storage filter capacitor

 discharges through the resistor 14 faster than the energy idle pump for the account; pulses produced by a controlled oscillator // signals, and as a result, the incident on the storage capacitor of the filter 13 drops. Thus, the voltage across the storage capacitor of the filter 13 and the adjustable resistor 14 is dependent on the voltage applied to the regulating element 6. With the necessary insulation of the output winding and the inverter 4 and the output winding of the controlled oscillator, the signal is achieved between the elements predavtiglnogo and main stabilizers on the maximum high incidence of the stabilizer. At the divided working potentials of elements of the preliminary and main stabilizers elements

The pre-stabilizer and transducer are not high voltage iodine.
