What are the advantages of high-voltage input module power supply?(2)

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.

(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 Marine boost 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.

(4) high-voltage input module Marine boost 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) high-voltage input module Marine boost power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

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