Annotation: The paper outlines the way to realize charge devices module for space application on the basis of buck-converter with the passive snubber cell. Work analysis of the snubber, simulation of processes in the converter were made as well as switching oscillograms and coefficient efficiency of the converter on the basis of the scale model were taken. Based on the research results, the conclusion about advantages and disadvantages given snubber was made.
