4, the use environment of product of communication direct current source is complex with each passing day
Inchoate communication equipment bureau stands, it is indoor model equipment, use in communication equipment room. But the development as mobile and the requirement to covering range, and stem from construction cost consideration, the user asks to be able to provide the requirement that satisfies all sorts of application environments and requirement, like system of requirement communication direct current source can outdoor use, hanging installation, built-in to communication advocate equipment aircraft ark is as medium, common as batteries a variety of application environments such as machine ark, installation relying on a wall and installation means.
5, the demand of carry dimension cost of product of communication direct current source is lower
User of product of communication direct current source needs to pay in facility construction initial stage purchase cost, during move need pays a computer room to use charge, electric power fee, safeguard personnel expenses, safeguard material charge to wait. The user of product of communication direct current source cares a product more and more now whole lifecycle cost and charge, each respect has this carry safeguard with respect to hope product lower cost.
2, the technology of product of communication direct current source develops
Technology of product of communication direct current source is a technology that uses a sex, its involve the fundamental technology of many course and domain, for example technology of electronic parts technology, commutation of electric power electron, computer technology, craft production technology. The technology of these domains expands the development that promoted technology of power source application, make development of technology of communication direct current source close level reflects following features:
1, interior of product of communication direct current source is departmental the development existence disequilibrium that divides a technology quality
Product of communication direct current source is general by hand in, a few parts such as system of dc distribution unit, rectifier unit, monitoring unit, accumulator are formed, but the technical development of this a few parts is disequilibrium. Develop among them the fastest is rectifier technology, and distribution technology develops relatively slow, brought about interior of system of whole communication direct current source so the disequilibrium of departmental cent develops.
2, new-style parts of an apparatus and material receive ceaseless application
The ceaseless emerge in large numbers of new-style parts of an apparatus and material is applied in product of communication direct current source. For example carborundum (SiC) parts of an apparatus and new-style and magnetic material (if be not brilliant material) in beginning to apply communication to use rectifier stage by stage, DSP chip also begins to receive dimensions application in rectifier. More high-powered sheet piece engine system gets applied ceaselessly in monitoring unit, colloid batteries gets applied in great quantities waiting.
