Overview of technical development of communication DC switching power supply products
The product technology of communication DC switching power supply is an applied technology, which involves the basic technologies of many disciplines and fields, such as electronic device technology, power electronic conversion technology, computer technology, process manufacturing technology, etc. The technical development of these fields has promoted the development of power supply application technology, which makes the development of communication DC switching power supply technology reflect the following characteristics in the recent stage:
1 communication DC switching power supply products internal development of various parts of the technology is uneven.
Communication DC switching power supply products are generally composed of AC and DC power distribution units, rectifier units, monitoring units, battery systems and other parts, but the technical development of these parts is uneven. The rectifier technology develops fastest, while the power distribution technology develops relatively slowly, which leads to the uneven development of all parts in the whole communication DC switching power supply system.
New devices and materials have been continuously applied.
New devices and materials are constantly emerging and applied to communication DC switching power supply products. For example, silicon carbide (SiC) devices and new magnetic materials (such as amorphous materials) are gradually applied to communication rectifiers, and DSP chips are also applied to rectifiers on a large scale. Higher-performance single-chip microcomputer systems are constantly applied to monitoring units, and colloidal batteries are widely used.
3 power conversion technology continues to develop
As the core component of communication DC switching power supply, rectifier has developed most rapidly in technology, and various new line technologies, switching converter technologies, resonant switching technologies, new soft-switching technologies, power factor correction technologies, loop control technologies and current sharing technologies are developing rapidly and being commercialized in products.
4 New monitoring technologies are constantly being applied.
With the development of computer technology, some new technologies are constantly applied in communication DC switching power supply products, such as CAN bus technology, IP communication technology, USB technology, networking technology based on Internet, etc. The application of these technologies promotes the intelligent development of communication DC.
