What are the advantages of isolated module 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;

high frequency switch
The rapid development of the communication industry has greatly promoted the development of communication power. High frequency miniaturized switching power supply and its technology have become the mainstream of modern communication power supply system. In the field of communication, the rectifier is usually called the primary power supply, and the direct current-direct current (DC/DC) converter is called the secondary power supply. The role of the primary power supply is to convert the single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V. In the primary power supply for program-controlled switches, the traditional phase-controlled regulated power supply has been replaced by a high-frequency switching power supply. Controlled in the 50-100kHz range for high efficiency and miniaturization. In recent years, the power capacity of switching rectifiers has been continuously expanded, and the single-unit capacity has been expanded from 48V/12.5A, 48V/20A to 48V/200A, 48V/400A.

(2) isolated module power supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

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

The size of the magnetic components is closely related to the switching operating frequency. Within the allowable operating frequency range of the magnetic components, the size of the magnetic components is inversely proportional to the switching operating frequency. To reduce the high-frequency switching transformer and inductance of the module switching power supply The volume of magnetic components and other magnetic components need to increase the switching frequency.

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

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

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

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