(large dynamic range), for the consideration of reliability, when big multipair power supply carries out statistical test, power taking source
Output minima, and on the basis of minimum power, the fixing output control that design matches
System processed.As it is shown in figure 1, after general distribution system uses fire zero line rectifying and wave-filtering mostly, add linear electricity
Source, to the multiple system power supply of rear class, when its own system heavier loads, causes the voltage after rectified wave filter
Time too low, due to from same source, it will cause the linear power supply of other system normally to work.
Such as in intelligent electric meter field, the transformator that used due to different ammeters or concentrator or open
Closing and there is certain difference between power supply, under different output voltages, output also exists bigger
