Embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.
See also Fig. 2, the utility model provides a kind of distributed uninterrupted DC power supply, comprises AC/DC module 10, step-down DC/DC module 20, storage battery 30, isolating diode 40 and output DC/DC module 50; One end of the output of said AC/DC module 10 connects the input of said step-down DC/DC module 20; The other end directly connects said output DC/DC module 50; The output of said step-down DC/DC module 20 connects the input of said storage battery 30, and said storage battery 30 outputs connect the input that connects said output DC/DC module 50 through isolating diode 40.
Be different from Portable DC power supply of the prior art when the AC power dead electricity; Give the electricity consumption electric by the storage battery in the DC power supply through DC/DC boost module and final stage DC/DC module; Cause the defective that the battery tension loss is high, power supplying efficiency is low and power-on time is short; The distributed uninterrupted DC power supply of the utility model is employed between storage battery and the output DC/DC module and connects an isolating diode, utilizes the low characteristics of diode forward conduction pipe pressure drop, battery tension loss in the time of can being reduced in AC/DC module no-output; Improve the power supplying efficiency of storage battery, can prolong the operating time of storage battery simultaneously.
Said AC/DC module 10; Comprise a bridge rectifier module and a ground capacity; The voltage transitions of alternating current 220V ± 20% is become than higher direct voltage, and this voltage is designed to higher than storage battery 30 voltages, simultaneously with storage battery 30 voltages all in the permission input range of output DC/DC module 50.Step-down DC/DC module 20 output is fit to the voltage of charge in batteries, storage battery 30 under the situation that exchanges dead electricity the continual power supply that provides to output DC/DC module 50.Isolating diode 40 is isolated AC/DC module 10 and storage battery 30.Output DC/DC module 50 output system voltages, the input voltage range of output DC/DC module 50 is greater than the voltage of storage battery 30 scope to AC/DC module 10 output voltages.
Explanation more specifically, when Alternating Current Power Supply, AC/DC module 10 output dc voltages directly offer output DC/DC module 50, output system voltage.Offer step-down DC/DC module 20 simultaneously, the voltage that 20 outputs of step-down DC/DC module are fit to storage battery 30 chargings charges to storage battery 30, makes storage battery 30 remain saturation condition.The direct voltage of AC/DC module 10 outputs and battery tension all in the permission input range of output DC/DC module 50, make exchanging dead electricity, need not battery tension is boosted during by storage battery power supply.Storage battery 30 outputs are through receiving the input of output DC/DC50 behind the isolating diode 40.Because voltage ratio storage battery 30 voltages of AC/DC module 10 outputs are high, so diode operation realizes the output and storage battery 30 isolation of AC/DC module 10 in cut-off state.
When exchanging dead electricity; AC/DC module 10 does not have voltage output; The isolating diode 40 of this moment is operated in conducting state, and storage battery 30 for the output DC/DC module 50 continual power supplys that provide, makes system through isolating diode 40 when exchanging dead electricity; Still can bio-occlusion electricity consumption electric, guarantee the normal operation of system.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
