Abstract

To solve the problems of low efficiency, large loss, and slow dynamic response of traditional DC/DC converters in aircraft power systems, and to improve the performance and reliability of aircraft electrical systems, this paper first summarizes the basic principle, working characteristics, and application status of phase-shifted full-bridge DC/DC converters in different fields, focusing on the potential value in aircraft system power management. Subsequently, a detailed simulation model of the phase-shifted full-bridge DC/DC converter is built based on the MATLAB/Simulink platform. The feasibility of the design is verified through simulation experiments. The development results show that the power conversion efficiency is effectively improved. In addition, the verification results of the simulation model provide an important reference for the design, selection, and fault prediction of DC/DC converter in aircraft power systems, which is of great significance for improving the performance and reliability of the overall aircraft electrical system.
