Background technology
AC-DC converter and DC-DC converter have that volume is little, lightweight, conversion efficiency advantages of higher, and are widely applied in the middle of from industry to civilian every field.But, along with extensively promoting the use of of AC-DC converter and DC-DC converter, also along with a series of use problem, particularly, logic semiconductor chip ultra-large is in recent years at high speed development, the chip consumed powers such as CPU, GPU, FPGA in high-speed computer and industry control constantly increase, and computer is to the power of AC-DC and DC-DC converter and reliably have higher requirement.Along with consumed power constantly increases, be subject to again the restriction of the input power of AC-DC and DC-DC converter, converter power output is caused also to be restricted, when using single AC-DC or DC-DC converter to export very high-power, input power reguirements is uprised accordingly, add power supply cost, and the reliability of converter is also deteriorated.
Utility model content
The purpose of this utility model is to solve the problem and proposes a kind of AC-DC and DC-DC mixing transformation device, and this mixing transformation utensil has good reliability, the advantage that cost is low.
In order to realize such scheme, the technical scheme that the utility model is taked is as follows:
The utility model proposes a kind of AC-DC and DC-DC mixing transformation device, it is characterized in that: comprise AC-DC converter and DC-DC converter.
Rectifier, power factor improvement circuit, the first DC-DC converter that described AC-DC converter comprises ac input end and is connected with described ac input end, described rectifier carries out rectification to the alternating current that ac input end inputs, the input of described power factor improvement circuit is connected with the output of described rectifier, and the output of described power factor improvement circuit is connected with described first DC-DC converter input.
The second DC-DC converter that described DC-DC converter comprises direct-flow input end and is connected with described direct-flow input end, described second DC-DC converter is connected with the output of described first DC-DC converter.
Further, the first capacitor for putting aside energy is also connected with between described power factor improvement circuit and the first DC-DC converter.
Further, the second capacitor for filtering is also connected with between described direct-flow input end and described second DC-DC converter.
The beneficial effects of the utility model:
1. limit by input power with traditional power output, increase input power supply portion after power output will to change and converter also can become expensive AC-DC converter and DC-DC converter is compared, a kind of AC-DC and DC-DC mixing transformation of the utility model device can simultaneously with the supply of AC and DC power supply, one of them converter does not affect another converter work after damaging, and under high power applications, AC-DC and DC-DC mixing transformation device is more reliable cheap;
2. few, the structure of the utility model electric elements is simple, easy-to-connect and the integrated convenience of circuit.
Accompanying drawing explanation
Fig. 1 is the circuit theory diagrams of a kind of AC-DC and DC-DC mixing transformation of the utility model device.
Wherein, 1-rectifier, 2-power factor improvement circuit, 3-first DC-DC converter, 4-second DC-DC converter, 5-first capacitor, 6-second capacitor.
Embodiment
In order to the technical scheme clearly, in complete explanation the utility model embodiment, below in conjunction with the accompanying drawing in the utility model embodiment, the utility model is further described.
As shown in Figure 1, the utility model proposes a kind of AC-DC and DC-DC mixing transformation device, comprise AC-DC converter and DC-DC converter.
Rectifier 1, power factor improvement circuit 2, first DC-DC converter 3 that AC-DC converter comprises ac input end and is connected with described ac input end, the alternating current of described rectifier 1 pair of ac input end input carries out rectification, the input of described power factor improvement circuit 2 is connected with the output of described rectifier 1, and the output of described power factor improvement circuit 2 is connected with described first DC-DC converter 3 input.Ac input end can obtain alternating current from the general socket of civil power, and then alternating current is delivered to rectifier 1, and now, rectifier 1 one aspect is carried out rectifying and wave-filtering to alternating current and alternating current is become direct current, carries out electric power storage on the other hand the first capacitor 5 of savings energy; Direct current after transformation is delivered to the first capacitor 5 via power factor improvement circuit 2 again after the adjustment of power factor improvement circuit 2, is finally transported to the first DC-DC conversion circuit 3 and changes.
The second DC-DC converter 4 that DC-DC converter comprises direct-flow input end and is connected with described direct-flow input end, described second DC-DC converter 4 is connected with the output of described first DC-DC converter 3.Direct-flow input end can obtain direct current from high pressure DC electrical network, and direct current is transported to the second DC-DC converter 4 through the filtering of the second capacitor 6.
As a kind of preferred version, between described power factor improvement circuit 2 and the first DC-DC converter 3, be also connected with the first capacitor 5 for putting aside energy; The second capacitor 6 for filtering is also connected with between described direct-flow input end and described second DC-DC converter 4.
Limit by input power with traditional power output, increase input power supply portion after power output will to change and converter also can become expensive AC-DC converter and DC-DC converter is compared, a kind of AC-DC and DC-DC mixing transformation of the utility model device can simultaneously with the supply of AC and DC power supply, one of them converter does not affect another converter work after damaging, and under high power applications, AC-DC and DC-DC mixing transformation device is more reliable cheap.In addition, the output of the second DC-DC converter 4 and described first DC-DC converter 3 is connected and makes: one, be connected with the DC-DC converter lead-out terminal voltage that exports of AC-DC converter is equal; Two, AC-DC converter and one of them converter of DC-DC converter do not affect other converter work after damaging; Three, AC-DC converter and DC-DC converter share the half of AC-DC and DC-DC mixing transformation device gross power separately.The utility model can effectively reduce cost and improve the reliability of converter.
Only as described above, be only the preferred embodiment of the utility model, certainly the scope of this novel enforcement can not be limited with this, namely generally make simple equivalence change according to the content described in the utility model claim and utility model specification and modify, all still belong within the utility model claim scope.In addition, summary part and title are only used to the use of auxiliary patent document search, are not used for the interest field of restriction the utility model.
