Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, the miniature alternating current-direct current Intelligent Composite power supply that the utility model provides can be all simultaneously for the DC equipment of 4G mobile base station arranges power supply with exchanging.
As shown in Figure 3, an embodiment of the present utility model comprises AC/DC rectification module, DC/AC inversion module, alternating current input, alternating current output, DC output end and storage battery; Wherein, the input of alternating current input and AC/DC rectification module couples; Output and the DC output end of AC/DC rectification module couple; The output of AC/DC rectification module also couples with the charging input end of storage battery; The output of AC/DC rectification module also couples with the input of DC/AC inversion module; The output of DC/AC inversion module and alternating current output couple; The input of the output of described storage battery and DC/AC inversion module couples, and also couples with DC output end; Described alternating current input is also couple to alternating current output by alternating current bypass switch.
The present embodiment has normal operation and two kinds of working methods of emergency operating.
Normal operation is divided into again the main confession of civil power and initiatively two kinds of patterns of equipment.
Civil power is main under pattern, in the time that the alternating current (being generally civil power) of inputting is normal (220V/7A), (nominal value is-48V to the direct current of civil power by be converted into-48V of AC/DC rectification unit standard, but virtual voltage may be between-40 ~-58V), and be base station DC equipment power supply by DC output end, accumulators group charging simultaneously, also to export to alternating current output by alternating current bypass switch be the power supply of base station alternating current equipment to civil power on the other hand, DC/AC inversion module synchronously leaves standstill backup and waits for, basic idle.This kind of state occupies the groundwork time.
