Design of Miniaturized Low-Voltage Switching Power Supply for Airborne

With the development of miniaturized power supply [1] for airborne power supply, the requirements of miniaturized power system for the whole machine are getting higher and higher. Small size, high power, high voltage switching power supply has become the choice of more and more users. However, the power density of high-power small-volume power supply is large, and the realization of functional mode is difficult to design, which greatly inhibits the miniaturization development of high-power power supply. Through the analysis of different functional modules, the related functional modules are superimposed and integrated, which has achieved the miniaturization requirements and provides a new design scheme for practical engineering practice.
