Technical field
The utility model relates to a kind of D.C. high-current generator, is specifically related to the direct parallel connection direct strong current generator of a kind of multimode.
Background technology
D.C. high-current power supply more than the present 500A is owing to the reason on technology and the device causes structure very simple; All be that rectification provides big electric current output after directly using the transformer step-down; So output accuracy is all very low, and owing to have pressure drop on the commutator tube, according to P=U*I; Meeting loss lot of energy on commutator tube, so efficient is not high yet.In addition, so also owing to be the voltage accuracy of the uncontrollable output of rectification output.
The utility model content
The utility model technical matters to be solved just provides a kind of high-level efficiency and high-precision D.C. high-current generator.
The utility model addresses the above problem the technical scheme that is adopted:
A kind of D.C. high-current generator; It is characterized in that: comprise that the parallel connection of at least 2 step-down type dc generating module exports a parallelly connected junction station output to; Described step-down type dc generating module comprises step-down type dc current feedback circuit and sampling with high precision feedback controller, and the output of said step-down type dc current feedback circuit is through the DC voltage of sampling with high precision feedback controller control output high precision high stability degree.
Through a plurality of high efficiency step-down type dc current feedback circuits directly parallel connection output big electric current output is provided, do not have the current-sharing device during parallel connection, do not need parallel diode, therefore saved the power attenuation that produces when parallelly connected.Current-sharing between its a plurality of modules comes control automatically through sampling with high precision feedback controller module.Its principle is: through the output of each DC current generator of sampling; And feed back to the inner and setting value of step-down type dc current feedback circuit and compare; The output voltage precision of strict each DC current generator of control; The output error of each step-down type dc current feedback circuit is remained on below 5/10000ths; According to Ohm law
, on R, just can not produce electric current so if when parallel connection U is the same.Just can be through a plurality of high precision step-down type dc of parallel connection generating module directly for output terminal provide big electric current, and efficient is very high, can reach the efficient more than 85%.
The direct parallel connection direct strong current generator of a kind of multimode of the utility model is simple in structure, and directly parallel connection output provides stable, big electric current is exported efficiently thereby make a plurality of modules through technological innovation.And stable performance, have very high practicality.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described:
See also accompanying drawing; The direct parallel connection direct strong current generator of the multimode of the utility model schematic diagram; Shown in accompanying drawing, multimode directly parallel connection output D.C. high-current generator comprises the first step-down type dc current feedback circuit 1, the second step-down type dc current feedback circuit 2, the 3rd step-down type dc current feedback circuit 3, n step-down type dc current feedback circuit 4, the first sampling with high precision feedback controller 5, the second sampling with high precision feedback controller 6, the 3rd sampling with high precision feedback controller 7, n sampling with high precision feedback controller 8, parallelly connected junction station 9.Wherein, said n step-down type dc current feedback circuit 4 is a n step-down type dc current feedback circuit of parallel connection, and said n sampling with high precision feedback controller 8 is the sampling with high precision feedback controller of n parallel connection.
The said first sampling with high precision feedback controller 5 is gathered the output of the first step-down type dc current feedback circuit 1 and is fed back to the first step-down type dc current feedback circuit 1, makes 1 output of the first step-down type dc current feedback circuit stablize high-precision DC voltage.The said second sampling with high precision feedback controller 6 is gathered the output of the second step-down type dc current feedback circuit 2 and is fed back to the second step-down type dc current feedback circuit 2, makes 2 outputs of the second step-down type dc current feedback circuit stablize high-precision DC voltage.Said the 3rd sampling with high precision feedback controller 7 is gathered the output of the 3rd step-down type dc current feedback circuit 3 and is fed back to the 3rd step-down type dc current feedback circuit 3, makes 3 outputs of the 3rd step-down type dc current feedback circuit stablize high-precision DC voltage.Said n sampling with high precision feedback controller 8 is gathered the output of n step-down type dc current feedback circuit 4 and is fed back to n step-down type dc current feedback circuit 4, makes 4 outputs of n step-down type dc current feedback circuit stablize high-precision DC voltage.The output of said n step-down type dc current feedback circuit provides big electric current output after parallelly connected junction station 9 parallel connections.
Because each step-down type dc current feedback circuit is all exported through the control of sampling with high precision feedback controller; Output through each module of sampling; And feed back to the inner and setting value of step-down type dc generator and compare; The output voltage precision of strict each module of control; The output error of each step-down type dc generator is remained on below 5/10000ths; According to Ohm law
, on R, just can not produce electric current so if when parallel connection U is the same.The output accuracy of module is very high, and the pressure reduction between each module is very little, and there are slight resistance in lead that when parallel connection, uses and joint, therefore when parallel connection between module and the module no big electric current flow, realized that direct parallel connection provides big electric current to export.
Directly parallel connection output D.C. high-current generator architecture is simple for the utility model multimode, makes it that big electric current output can be provided through technological innovation, and stable performance, and efficient is high, has very high practicality.
