A modular hierarchical power supply and distribution method is proposed for electrical system of launch vehicles in order to avoid large scale power supply cable, complex topology and potential path. Each stage of electrical system is planned as an independent power supply and distribution unit, and the integrated power supply and distribution framework is realized in the unit. Electrical isolation is designed among different power supply and distribution units and ground equipment to prevent the electrical coupling and potential circle path and reduce the system complexity. The power and distribution system has the advantage of modularization in system level and the plug and play with units, which provides a technical basis for the standardized design of the power supply and distribution structure of the future electrical system and hierarchical test of the launch vehicle.
