1 communication DC switching power supply products internal development of various parts of the technology is uneven.

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.
