A Scalable Architecture Platform for Spaceborne High Power Power Controller

Abstract

The invention discloses an expandable structure platform for a space-borne high-power power supply controller, which includes: a plurality of functional modules, a remote control telemetry rigid-flex printed board, a main error amplifier EMA module, a bus bus bar of the whole machine, an upper cover plate, a rear cover plate and side cover plate; the functional modules include three types, namely charge and discharge regulation module, shunt regulation module and remote control telemetry module; the quantity of charge and discharge regulation module and shunt regulation module is selected according to the power design target; each functional module The main structure is a hollowed-out pentahedron structure; each functional module is placed vertically and stacked together, and then the side cover is installed, and the functional modules are connected to each other through protruding ears; the functional modules are installed in the cavity on the top Remote telemetry rigid-flex printed board, the EMA module and the bus bar of the whole machine are respectively installed in the two rear cavities. The interior of the functional modules adopts a layered three-dimensional layout. The invention can meet the environmental test requirements of the space-borne electronic equipment and meet the heat dissipation requirements of the whole 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
