SU493914A1 - Voltage to frequency converter - Google Patents

Description

is switched over the full cycle, varies from -BS to, we find the relation that determines the dependence of the frequency / output signal on the control voltage Uy:

W ,,

and f

 Qi

where Qi is the cross section of the core of the transformer 3. From the obtained expression it can be seen that the dependence of the frequency on the control voltage here is linear with both positive and negative values of y.

The duration of the transient process with a jump-like change in the control signal does not exceed the half-period, since the rate of change in the flux linkage in core 8 and, therefore, in core 3 is determined by the instantaneous voltage values.

The current consumption from the control source is insignificant.

Subject invention

A voltage-to-frequency converter made on a magnetic-coupled multivibrator containing two transistors, a first transformer with collector and base windings, and a second transformer with y windings; the right (Arrows connected relative to each other, keys with control circuits differing in what with

In order to simplify, the collector windings additionally cover the core of the second transformer, and both cores are covered with additional windings connected in antiphase to the key control circuits.
