Reduction of Calculations of Characteristics of Electronic Components Based on System Analysis

Purpose of research. When designing electronic devices, there is a need to perform a large number of calculations in the selection of individual electronic components. Therefore, the purpose of the study is to reduce the calculations of the characteristics of electronic components of circuits by applying the methods of system analysis.

Methods. The paper considers the presentation of the sequence of calculating the characteristics of electronic components as a multidimensional discrete stationary system, to the input of which the conditions of use and physical properties of the components are supplied, as well as the use of system analysis to reduce the calculations of the characteristics of electronic components of circuits using the example of a choke in the design of electronic devices.

Results. The application of the methods of system analysis to reduce the time of calculating the characteristics of electronic components in the design of devices is considered.

Conclusion. To create a highly efficient switching power supply, one of the main tasks is to calculate the core and winding of the choke. When choosing an inductor, it is necessary to select and calculate the core, calculate the winding and select the choke that meets the given initial criteria. Each manufacturer of toroidal cores supplies a description and means of calculating characteristics only for their products and in a convenient non-standardized format only for themselves, which leads to a lot of manual work in calculating the characteristics of the cores, winding and comparative analysis of the results obtained to select the most suitable option in the conditions the task at hand. The presentation of the sequence of calculating the characteristics of electronic components in the form of a multidimensional discrete stationary system allows you to reduce the time for calculating the characteristics of electronic components by reducing their volume.
