Product of communication direct current source develops a tendency
From;    Author:Stand originally

3, power transformation technology develops ceaselessly
Regard the core of communication direct current source as the component---Rectifier, develop on the technology most rapid, road of corrective technology, annulus controls factor of technology of all sorts of new-style line technologies, switch transformer technology, syntonic switch technology, new-style soft switch, power technology, all shed a technology to developing quickly ceaselessly and get applied in the product.
4, new monitoring technology applies ceaselessly
Accompanying the development of computer technology, a few new-style technologies also are corresponding ceaselessly get applied in product of direct current source, if technology of CAN bus line, IP corresponds the technology, USB technology, group net technology that is based on internet. The application of these technologies drove the intelligence of communication dc to change development.
3, the development trend of product of communication direct current source
In demand and technology drive jointly below, product of communication direct current source reflected the development situation that be as follows:
1, systematic framework maintains stability inside quite long period of time
Communication direct current source still maintains module of existing communication distribution, commutator inside quite long time (shunt-wound) , the unit of dc distribution, monitoring, accumulator framework that is main component; Power transformation mode also will maintain pattern of existing high frequency switch, won't appear temporarily similar arrive from linear power source of switch power source rank the change that jump a gender.
2, power density rises ceaselessly
Correspond the power density of the core component commutator of power source rises ceaselessly, drove the power density with communication overall direct current source to rise ceaselessly, but the density such as distribution parts of an apparatus, accumulator maintains stability basically, certain level was restricted overall of power density of the system raise rate.
3, higher reliability
High reliability is the mainest demand of communication power source. As the maturity of technology of technology of parts of an apparatus, communication power source, and manufacturer of equipment of each communication direct current source is thrown energetically on dependability research, reliability of product of communication direct current source shows the trend that raises ceaselessly.
4, low cost
Of market price case glide ceaselessly, drove manufacturer home to reduce the cost of the product ceaselessly. But too low cost also can bring certain negative effect, what function restricted on certain level is ceaseless rise.
5, higher performance
The performance system with more expensive product of communication direct current source is the following now respect:
· changeover efficiency is taller and taller, work actually especially the changeover efficiency below the circumstance;
· should satisfy more new standards, wait for a standard like EMC, safe, environmental protection;
