[0003] At the same time, the redundant power supply system is a complex system with multiple subsystems working together. Each component needs to meet specific conditions to achieve the overall performance index. The existing redundant power supply schemes in various fields have not explained the setting method of key matching parameters. , there may be consequences caused by adaptation problems between systems, especially the problem of power failure and restart of components that may be caused by the short circuit of the main power supply to the switching process of the power supply. With the continuous improvement of safety requirements, it is particularly important
