Abstract

The invention provides a low-voltage intelligent direct current power supply system and an operation method, the input end of an AC / DC module is connected with an external power supply, and the output DC port of the AC / DC module is connected with a DC / DC module; the control module is connected with the AC / DC module and controls the AC / DC module to output the output voltage of the DC port; the output side of the DC / DC module is connected with a load through a bus; the power supply end of the energy storage battery is connected with a load through the discharge module and the DC / DC module, and when the external power supply loses power unplanned, the energy storage battery provides energy for the load; the output side of the DC / DC module is connected with the energy storage battery through the charging module and charges the energy storage battery according to the control instruction of the control module. High-power, high-efficiency, multi-port and multi-direct-current-voltage-level output is achieved, power can be directly supplied to buildings, industrial systems and the like, and the power utilization requirement is met.

Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to a low-voltage intelligent DC power supply system and an operating method. Background technique [0002] With the continuous development of switching power supply technology, high-power switching power supply occupies an increasingly important position in all walks of life. At present, high-power switching power supply is developing towards high frequency, high power, high efficiency, high reliability, high power density, and digitalization. Low-voltage high-power switching power supply has the characteristics of being able to output low-voltage and high-current, and has been applied in many heavy industrial fields. [0003] Currently, DC-DC converters of about 1kw are mainly used in DC power supplies. This kind of converter has low power and relatively low performance; while a system with high power requires a large space volume, low conversion efficiency, and i...
