What are the advantages of high-voltage input module power supply?(1)
The switching power supply module, in short, is to obtain a higher power vehicle module power supply supply through some modifications. In fact, the internal circuit of the switching power supply module is actually a switching power supply. So, what are the advantages of switching power supply modules? What are its main applications?
1. What are the advantages of switching power supply modules?
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the primary power supply for program-controlled switches, the traditional phase-controlled regulated power supply has been replaced by a high-frequency switching power supply.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.
There are many advantages of switching power supply modules:
(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) high-voltage input vehicle module power supply supply The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
