Research of Frequency Characteristics of DC-DC Switching Converters ICs

The article proposes the methods for determining the frequency characteristics of DC-DC switching converter microcircuits. Using computer modeling, the feasibility of the technical implementation of the proposed method in the form of a control and measuring device is substantiated. Also, the article considers a method for determining the frequency characteristics of the models of DC-DC switching regulators microcircuits. The method is based on the use of correlation analysis when finding the steady-state stationary mode of the modeled object in the time domain with a varying frequency of the harmonic input effect. This method allows reducing the amount of calculations when obtaining the frequency characteristics of the models of DC-DC switching converter microcircuits. The material in the article is of value for the manufacturers of microcircuits of this class and developers of DC-DC switching converters.
