The invention discloses a bus-type power distribution architecture adaptive to an extensible micro-nano satellite platform, relates to the field of micro-nano satellites, and aims to solve the problems that an existing satellite power supply and distribution system is complex in architecture, each device is difficult to support more peripherals due to an independent power distribution cable, the expansibility is poor, and the cable topology is complex. The system comprises a 1-Wire bus, a bus power supply and a power distribution unit, a bus power supply is adopted to provide power for each single machine, local power-on and power-off control and telemetering parameter return of each single machine are realized through a 1-Wire bus, and the power distribution unit realizes power-on and power-off control of electric equipment; according to the high-reliability power distribution bus architecture based on the single bus, extremely simplified cable topology is adopted, power distribution control and feedback quantity collection of on-satellite equipment are achieved, double-bus cross backup is easy to achieve so as to ensure reliability, and the architecture has good expandability, can support hundreds of equipment and is high in reliability. And the method is very suitable for a micro-nano satellite platform with relatively high expansibility requirements.
