According to the dual-system parallel power supply device and method, on the premise that the basic stage and the upper stage of a carrier rocket are mutually independent systems, a basic stage power distributor is divided into an upper stage power distribution output module and a basic stage power distribution output module; the upper-stage power distributor can receive upper-stage ground power supply and power conversion instructions and can also receive power distribution output and power conversion instructions of the basic stage. According to the dual-system parallel power supply device and the dual-system parallel power supply method, during ground test and flight, the basic level provides working power for the upper level in the flight section of the basic level, so that the battery consumption of the upper level is reduced. 本发明公开了一种双系统并联供电装置与方法，在运载火箭基础级与上面级互为独立系统的前提下，基础级配电器分为"上面级配电"输出和"基础级配电输出"两个模块；上面级配电器既能接收上面级地面供电和转电指令，又能接收基础级的配电输出和转电指令。本发明的双系统并联供电装置与方法，在地面测试和飞行时，基础级飞行段由基础级向上面级提供工作用电，降低了上面级电池消耗。
