The main scientific problems of building domestic aggregated (complex) devices and distributed power supply systems and the reasons for their characteristics lagging behind modern foreign analogs

Abstract

The main problems of building domestic secondary power supply systems are considered. It is shown that the main problem in the construction of power supply systems with two- and three-time power conversion is the problem of stability. It is shown that separate subsystems with negative feedback operating in an autonomous mode with large stability reserves in amplitude and phase, being integrated into a single system because of mutual influence on each other, can be excited. The importance of determining the frequency characteristics of voltage converters is shown. The reasons for the lag in the characteristics of secondary power supply systems from modern foreign analogs are shown.
