Conclusions
-
1.
Formulas have been obtained for the instrumental and nonlinearity errors of units in a VCC with compensating integration, and its advantages over a VCC with series counting have been determined.
-
2.
It has been shown that the nonlinearity error of a VCC with compensating integration is cancelled completely for t2=t1, and will be less than the nonlinearity error of a series counting VCC for t2>t1/2.
-
3.
Principles have been established for the optimal selection of the value of Uref depending on the distribution law of the input signal.
-
4.
It has been shown that the errors in determining the time intervals and integrator elements affect the accuracy in a VCC with compensating integration considerably less than the corresponding errors in a series counting VCC. This makes a VCC with compensating integration the one with greatest prospects in the construction of a converter to work under difficult climatic conditions.
