Satellite-borne high-power power conditioning unit platform of extensible structure

Abstract

The invention discloses a satellite-borne high-power power conditioning unit platform of an extensible structure. The satellite-borne high-power power conditioning unit platform of the extensible structure comprises a plurality of function modules, remote control and remote measurement flex-rigid printed boards, main error amplifier EMA modules, complete machine bus bars, an upper cover plate, a rear cover plate and side cover plates, wherein the function modules comprises the charge-discharge conditioning modules, the shunt conditioning modules and the remote control and remote measurement modules, the number of the charge-discharge conditioning modules and the number of the shunt conditioning modules are determined according to a power design objective, the main body of each function module is of a wholly-hollowed-out pentahedron structure, the side cover plates are installed after all the function modules are vertically arranged in a stacked mode, every two adjacent function modules are connected with each other through a protruding lug, each remote control and remote measurement flex-rigid printed board is installed in a cavity in the top of the corresponding function module, each error EMA module and each complete machine bus bar are installed in two cavities in the back side of the corresponding function module respectively, and the overall arrangement of the interior of each function module is layered and three-dimensional. The satellite-borne high-power power conditioning unit platform of the extensible structure can meet the environmental testing requirement of satellite-borne electronic equipment and can also meet the heat radiating requirement of a complete machine.

Description

technical field [0001] The invention relates to the technical field of structural design of on-board electronic products, in particular to an expandable structure platform of an on-board high-power power supply controller. Background technique [0002] The power controller (PCU: Power Conditioning Unit) is the core equipment of the satellite power system. It is composed of several charge and discharge regulation (BCDR) modules, shunt regulation (S3R) modules, and remote control and telemetry (TMTC) modules. It plays a role in regulating solar cells. , The role of power balance between the battery and the load. It undertakes the important task of providing a stable primary bus for the satellite and providing charge and discharge management functions for the battery, which is an important guarantee for the stable operation of the satellite throughout its life cycle. Therefore need to develop a kind of high-power power supply controller on the star. [0003] According to the ...

AI Technical Summary

Problems solved by technology

[0004] 1) The high-power power supply controller equipment is bulky and heavy, so the structural design must be able to meet the mechanical performance indicators of the on-board equipment

[0005] 2) The external output power of the high-power power supply controller is 6000W, and its maximum heat consumption is 360W. The structural equipment must be able to solve the heat dissipation problem of the heating device of the equipment

[0007] 4) The internal space of the power controller is very tight, and there are many large-scale and large-volume devices. The structural design must effectively use the internal space to realize the three-dimensional layout inside the module
