Description
technical field [0001] The invention relates to a satellite power controller (PCU), in particular to a satellite power controller, a testability verification method and a testability verification platform. Background technique [0002] Satellites are technology-intensive and complex high-tech products. Despite the guarantee of high reliability, satellites operate in a space environment full of vacuum, weightlessness, high and low temperature, strong radiation and full of unknown interference factors for several years or even ten years, and aging of components and failures are inevitable. In order to ensure the safety of the satellite and avoid the breakdown of the entire system caused by the failure of a single component, it must be quickly and effectively dealt with at the beginning of the failure to maintain the normal function of the system. To achieve the above technical requirements, it is necessary to carry out test design work starting from satellite design, to ensur...
