The invention provides a satellite autonomous power-up circuit after satellite-rocket separation, and a control method thereof. The novel autonomous power-up circuit is provided to replace an existingpower-up mode so as to improve the safety performance of a main satellite of a micro-nano satellite, and the control mode that the main satellite is allowed to be powered up by a carried satellite after separation of the main satellite and a rocket is achieved in the whole-satellite power-off state before satellite-rocket separation. The satellite autonomous power-up circuit after satellite-rocket separation comprises a bus switching circuit, a satellite-rocket separation enabling/disabling circuit and an energy autonomous management circuit. 本发明所述的星箭分离后卫星自主加电电路及其控制方法，提供一种新型自主加电电路以替代现有加电方式，以提高微纳卫星主星的安全性能，在星箭分离前整星断电状态下实现主星与火箭分离后搭载星允许加电的控制方式。星箭分离后卫星自主加电电路包括母线开关电路、星箭分离使能/禁能电路和能源自主管理电路。
