Distributed power supply management device

The invention discloses a distributed power supply management device, belongs to the technical field of power supply management, and solves the problem that the whole power supply system is broken down when a power converter has a fault due to the adoption of an independent single power supply. Electric energy of each storage battery is output to a corresponding power conversion circuit; power output by N power conversion circuits is connected in parallel and input to the power supply control signal input end of a power conversion output interface; a controller acquires output current of each power conversion circuit through a current sensor; the pulse width adjustment signal output end of the controller is connected with the pulse width adjustment signal input end of a driver; the driver outputs N sets of pulse drive signals to N power conversion circuits respectively; and the power supply control signal output end of the controller is connected with the power supply control signal input end of the power conversion output interface. The distributed power supply management device is suitable for power supply management.
