Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Methods of Determination Requirements for Control Device Electric Parameters of Voltage Converter A.V. ASADCHIY, A.I. SOLDATOV The urgency of the research and electrical parameters testing devices for voltage switch converter are shown. The block diagram of the device and it’s the connection to voltage converter are presented. The description of the control device operation and its interaction with the voltage converter is given. A technique for determining the optimal parameters of the control device: the sampling frequency of the ADC and memory for date, so that the reconstructed signal has the specified error. The graphs of the reconstructed signal with the use of different numbers of harmonics are presented. An example of calculating the required amount of memory is given. Keywords: control device, converter of voltage, microcontroller, sampling, mathematical model, memory device. DOI: 10.25791/pribor.07.2020.1189 Pp. 18-24.
