Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a switch simulation device. Background technique [0002] Space payloads are usually powered by +28V and +42V busbars, and the +28V and +42V busbars are provided by satellite platforms. Satellites usually use relay switches to control power on and off for each payload. At the moment of power on and off, there are surges of different degrees. On the one hand, the surge will impact the busbar, and on the other hand, the surge may impact the space payload power supply system, which will seriously damage the space payload. [0003] Therefore, in the development stage of the space payload, it is necessary to conduct a considerable number of simulated power-on and power-off tests according to the on-orbit state, to expose various possible risks in the ground test, and to detect and solve potential problems early. [0004] However, in the actual ground test, the desktop ...
