What are the advantages of high-voltage input 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;
(2) high-voltage input 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;
At the same time, the design of the high-frequency switching transformer winding in the module switching power supply is also very important. The winding of the high-frequency switching transformer not only affects the copper loss, but also relates to the coupling between the high-frequency switching transformer windings, and also affects the iron loss of the high-frequency switching transformer. Influence, the design and manufacture of high-frequency switching transformers have a great impact on the performance of the module switching power supply
(4) high-voltage input module power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;
Diode rectification is used in traditional rectification, and Schottky diode rectification is generally used under low voltage output conditions. Compared with other rectifier diodes, Schottky diodes have the advantages of faster switching speed and lower forward voltage, but Schottky diodes The forward voltage drop of the diode is related to the size of the rectified output current. The larger the rectified output current is, the greater the forward voltage drop, which may be as high as 0.5~0.6V or more, and the reverse leakage current of the Schottky diode is larger. .
(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;
(6) high-voltage input 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.
