Abstract
The article presents equivalent circuit of the cycloconverter with natural commutation on the inter-commutation interval of operation for analyzing the converter control process. The method for determining the moving average on the switching cycle of the cycloconverter is proposed. The amplitude-frequency characteristic and the transfer function of the moving average excreta procedure are obtained. The steepness of the transfer characteristic of the cycloconverter by moving average is determined to define the parameters of the regulators in the feedback control system for the cycloconverter. Curves of the function of the average value of the modulation depth of the cycloconverter and the relative value of the steepness from the average value of the modulation depth on the clock are obtained. The proposed approximation on the cycle of the output circuit of the cycloconverter with natural commutation allows assessing the stability of the feedback control system using the concept of a moving average.
