Rectifier is the core of communication power supply system

and the development of its energy-saving technology affects the energy level of the whole communication system.The paper reviews the technology development course of communication power rectifiers systematically

and compares the main properties of the various stages.Furthermore

the results of simulation test show the efficiency of the rectifier reached 96.3%

increased by 4% than the average module

this conclusion suggests promoting the use of this highly efficient rectifier can be efficient and will save energy greatly

it will be the best choice for the future communication power.Based on theoretical analysis

through case studies

this paper extracts the quantitative indicators of this rectifier in energy saving and emission reduction

and proposes the practical suggestion on how to promotion this efficient rectifier.
