description: The aim of work is development a board for a powerful DC-DC converter using SEPIC technology for use in 12 volt communication equipment. An overview of existing solutions for the construction of pulsed DC-DC secondary power sources has been conducted. The advantages and disadvantages of various circuit solutions are determined. The basic principles of operation of a powerful DC/DC converter using SEPIC technology are considered. Circuit modeling is performed in the MicroCap environment. The calculation method, simulation results and the algorithm of the device operation are presented. A schematic diagram based on the NCV898031 integrated circuit has been developed. The circuit allows you to adjust the output voltage and output current. The schematic diagram and the printed circuit board of the device are developed in the EASYEDA online circuit editor. A printed circuit board of a powerful DC-DC converter using SEPIC technology has been developed. The board size was 80 * 100 mm2. The rated output voltage is 12 volts. The operating current in the load is up to 30 amperes. The developed device can be used to power devices in mobile communication equipment. Open educational resources and information search and analysis programs were used. Automation (automated) development tools such as EASYEDA was used. The Microcap software has been applied.
