Abstract
By means of mathematical modeling there have been studied regularities of electromagnetic processes taking place in the contactless excitation system of an asynchronous generator based on cascade, three-phase-three-phase voltage modulator. There have been found the regularities of these processes with the aim to examine the impact of changes in slip resistance of the generator on the stability of the switch operation and, as a result, on the stability of the excitation system and the generator as a whole. There is offered a method of adjusting parameters of the modulator rotor machine that allows stabilizing the switch and excitation system operation to get the sliding values sufficient for the generator to work in practice. The sliding range has been greatly expanded, up to two tenths, ensuring operation suitability of the asynchronous generator in this range
