ADAPTIVE HIGH SPEED MEASURING CONVERTER OF AVERAGE VOLTAGE VALUES

Abstract

The analysis of the measuring converter of average value voltage using the iteratively integrating method of conversion and its comparison with the analysis the generalized block diagram of the iteratively integrating measuring converter were performed. As a result of comparing the circuit of the measuring converter of average voltage values, which implements the iteratively integrating conversion method, with the generalized structural diagram of the iteratively integrating measuring transducer, the basic equations describing this device are obtained. As a result of the analysis of the generalized structural diagram of the iteratively integrating measuring transducer, an engineering solution is proposed that improves the parameters of the measuring converter of average voltage values by adapting it to the influence of changes in the input voltage frequency. This allows us to improve the dynamic characteristics of the converter of average voltage values when the input voltage frequency changes, which is directly related to the increase in the speed of the converter in the given frequency range of the input voltage or, which is equivalent in this case, to the extension of the frequency range of the input voltage, while maintaining the specified performance. It is proposed to adapt the considered converter of average voltage values to a change in the frequency of the input voltage periodically with a predetermined one, based on a priori information about the nature of the frequency change, periodically or occasionally, as the frequency changes.
