Pico-nano satellite power supply achieved through maximum power point tracking technology

The invention provides a pico-nano satellite power supply achieved through the maximum power point tracking technology and relates to the field of satellite power supplies. The pico-nano satellite power supply solves the problem that most of existing pico-nano satellite power supply systems are controlled through software and accordingly software defects lead to system failures. The power supply signal output end of a solar battery pack is connected with the power supply signal input end of a maximum power point tracking controller, the control signal output end of the maximum power point tracking controller is connected with the first control signal input end of a charge controller, the second control signal input and output end of the charge controller is connected with the first control signal output and input end of a storage battery protector and then connected to a bus, the second control signal input and output end of the storage battery protector is connected with the power supply signal output and input end of a storage battery pack, the control signal input end of a direct voltage conversion unit is connected to the bus, and the control signal input end of a power distribution unit is connected with the bus and the control signal output end of the direct voltage conversion unit at the same time and outputs voltage. The pico-nano satellite power supply is applied to supplying power to a pico-nano satellite.
