What are the advantages of non-isolated power supply?(2)

(1) It has a particularly wide range of uses, not only aerospace, post and telecommunications, but also metallurgy, mining, automatic control, etc., whether it is social production or daily life, it can be well used;

(2) non-isolated 48V input power supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

In the early 1980s, the research on the distributed high frequency switching power supply system basically focused on the research of the converter parallel technology. In the mid-to-late 1980s, with the rapid development of high-frequency power conversion technology, various converter topologies appeared one after another. Combined with large-scale integrated circuit and power component technology, it became possible to integrate small and medium power devices, thereby rapidly Promote the development of distributed high-frequency switching power supply system research. Since the late 1980s, this direction has become a research hotspot in the international power electronics field.

(3) The technology is relatively simple, and it is easy to meet the relevant requirements;

(4) non-isolated 48V input power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

The secondary power DC/DC converter of the communication power supply has been commercialized. The module adopts high-frequency PWM technology, the switching frequency is about 500kHz, and the power density is 5W~20W/in3. With the development of large-scale integrated circuits, the module power supply is required to be miniaturized, so it is necessary to continuously increase the switching frequency and adopt new circuit topologies. The power density of the module power supply has been greatly improved.

(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;

(6) non-isolated 48V input power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

 In many fields, switching 48V input power supply modules play a role that cannot be ignored and are very important.
