Abstract

The invention discloses a high-specific-power Buck circuit applied to a satellite power supply, which belongs to the technical field of space power supplies, and comprises an input end used for inputting a first voltage to a first Buck circuit and a second Buck circuit. The first Buck circuit is used for receiving the first voltage and outputting a second voltage to an output end together with thesecond Buck circuit; the first end of the first Buck circuit is connected with the input end; the second Buck circuit is used for receiving the first voltage and outputting the second voltage to theoutput end together with the first Buck circuit; the first end of the second Buck circuit is connected with the input end; the output end is used for receiving the control of the first Buck circuit and the second Buck circuit and outputting the second voltage; and the output end is connected with the second end of the first Buck circuit and the second end of the second Buck circuit. The high-specific-power Buck circuit applied to the satellite power supply provided by the invention has the characteristics of high specific power, low output current ripple, simple topological structure and highreliability.

Description

technical field [0001] The invention belongs to the technical field of space power supplies, and in particular relates to a high specific power Buck circuit applied to satellite power supplies. Background technique [0002] The space power supply system is one of the key subsystems to ensure the stable and reliable operation of the spacecraft. The DC-DC circuit is the main power circuit used in the existing space power supply system. The existing space power supply power circuits mostly use Buck, Boost, Boost-Buck and other topologies. . These topologies are simple and reliable, but have low specific power and large output current and voltage ripple. With the rapid development of my country's aerospace industry, the demand for power conversion circuits with high specific power and high output voltage and current quality in the new generation of satellite power supply systems is increasingly strong. [0003] Buck circuit is one of the most basic DC-DC conversion structures....
