(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) 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;

rectangular wave of 20 kHz.
Due to the poor working conditions of the welding machine power supply and frequent short-circuit, arcing and open-circuit changes, the working reliability of the high-frequency inverter rectifier welding machine power supply has become the most critical issue and the most concerned issue by users. . The microprocessor is used as the relevant controller of pulse width modulation (PWM), and through the extraction and analysis of multi-parameter and multi-information, the purpose of predicting various working states of the system is achieved, and then the system is adjusted and processed in advance to solve the problem. The reliability of high-power IGBT inverter power supply is improved.
Foreign inverter welding machines can achieve a rated welding current of 300A, a load duration rate of 60%, a full-load voltage of 60~75V, a current adjustment range of 5~300A, and a weight of 29kg.

AC-DC power module

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

reasonable core structure and compact structure.
At the same time, in order to reduce the size of the module switching power supply, the switching frequency of the module switching power supply should be increased as much as possible. If it is to be increased to about 500kHz or higher, the loss of the ordinary magnetic core material is very large, and the magnetic core is easily overheated and magnetically saturated, and even It cannot work normally, so the high-frequency magnetic core material with excellent magnetic properties must be selected in the module switching power supply.

(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.
