Description

technical field [0001] The invention belongs to the technical field of spacecraft ground testing and testing, and in particular relates to a program-controlled power supply series-parallel rapid configuration device. Background technique [0002] Vacuum thermal test is a costly and indispensable test project in the process of spacecraft development. In the cold and dark background, the outer space of the spacecraft in orbit is tested by infrared simulators (such as heating plates, infrared cages, infrared lamps, etc.). Heat flow simulations are performed to verify the correctness of the spacecraft thermal design. At present, the magnitude of the external heat flow absorbed by the spacecraft in the vacuum thermal test is mainly realized by controlling the computer and using the upper software to drive the program-controlled power supply to control the infrared simulator. The range of the program-controlled power supply output current (or voltage) directly determines the radia...

Problems solved by technology

Since the internal components of the program-controlled power supply have a certain withstand voltage value, manually connecting the power supply in series and parallel (especially in series) at the output terminal will easily cause the shared voltage of the two power supplies to be unbalanced, resulting in the series power supply exceeding the withstand voltage value of the device and causing the program-controlled power supply to fail. , which has a serious impact on the test; moreover, the testing party often temporarily proposes a series-parallel connection requirement for the power supply, and the series-parallel connection operation of the power supply output terminal is complicated and difficult to implement, and after the implementation, the cables and wires on site are staggered, posing safety hazards
