The power system provides the power for all electrical equipments on Launch Vehicle (LV). With the LV technology developing, the electrical power system integration and intelligent requirement of LV becomes stronger. For the disadvantages of the traditional power distribution technology for LV with relays, including few fault detection information, non-intelligent, too many lines between LV and ground equipments, a redundant and intelligent power distribution scheme for LV is proposed in this paper. The new scheme applies solid-state power controller (SSPC), distributed Bus, and intelligent data processing, redundant design, modular design, to achieve power distribution, fault isolation, built-in-test (BIT), and make the LV ground interface simple, and fit the requirement of new generation LV in the future. Prototype experiments showed that the scheme can provide all around protection, and realize independent management of power system.
