According to the report on China modular power supply market research and investment forecast (version 2021) released by Limu information consulting, the modular power supply is based on the switching power supply technology, using a small number of components combined with modular production. It is also a power conversion device. Because of the modular design, it has the advantages of miniaturization, moisture-proof, shockproof, good consistency, simple application and high reliability.
The module power supply can be directly attached to the power supply on the printed circuit board. Its characteristic is that it can supply power for application specific integrated circuits (ASIC), digital signal processors (DSP), microprocessors, memories, field programmable gate arrays (FPGA) and other digital or analog loads. Generally speaking, such modules are called point of load (POL) power supply system or point of use power supply system (pups).
Due to the advantages of modular structure, modular power supply is widely used in switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers and other communication fields, as well as automotive electronics, aerospace and so on.
In recent years, China's modular power supply market has shown a steady upward trend, and the industry scale is expanding rapidly. In 2018, the demand for modular power supply was about RMB 8billion, and in 2019, it was about RMB 8.59 billion, with a growth rate of 7.38%.
In terms of the market share of the industry, Emerson ranks first in the market by virtue of its comprehensive strength and influence in the power industry, followed by Ericsson, and VICOR ranks third in the market by virtue of its strong advantages in the military industry. In terms of domestic manufacturers, ruigu Technology (joint venture) and new leineng have developed rapidly and are at the leading level in China.
In recent years, the domestic substitution trend of various core components and parts in China will be further enhanced. In particular, the military field has determined that the demand for 100% localization of core components and parts such as modular power supply has given rise to large-scale domestic substitution space. Domestic modular power supply will usher in a period of rapid development. In high-performance power supply, especially in key military fields, the proportion of power supply localization will be rapidly increased.
