Extensible platform of power supply controller

Abstract

The invention provides an extensible platform of a power supply controller. The main structure of each structure module of the extensible platform of the power supply controller is a tetrahedral structure hollowed out as a whole and provided with a front panel, a rear panel, a top panel and a bottom panel, and hollowed-out grids are arranged in each module and include at least two layers of grids. Devices in each structure module are laid out three-dimensionally in the grids, so that internal space of the power supply controller is effectively utilized, and three-dimensional layout in the modules is achieved. A reinforcing frame not only provides an installation space but also connects all the modules as a main force bearing component of the whole controller, so that the strength of connection between the modules and the rigidity and the strength of the whole controller meet the requirements of a satellite mechanical environment. A capacitor (CAP) module is used for containing capacitors, the large number of capacitors are used in cooperation with the other modules to stabilize bus voltage, and thus good extensibility is achieved. Due to the use of installing holes and reverse-penetration holes, it is guaranteed that mechanical property requirements of device connecting pieces in the mechanical analysis and environment test process are met.

Description

technical field [0001] The invention belongs to the field of spaceborne technology, and in particular relates to an expandable platform of a power controller. Background technique [0002] The power controller is the core equipment of the satellite power system. It plays the role of adjusting the power balance between solar cells, batteries and loads, and undertakes the important task of providing a stable primary bus for satellites and providing charge and discharge management functions for batteries. An important guarantee for stable operation within the life cycle. [0003] At present, domestic high-power power supply controllers have various problems, such as inability to meet the heat dissipation requirements of equipment heating devices, and poor current transmission performance between modules between power supply controllers. These deficiencies reduce the key performance indicators of the power controller and affect the stable operation of the satellite throughout i...
