Inverter module power supply
High frequency inverter rectifier welding machine power supply is a new type of welding machine power supply with high performance, high efficiency and material saving, which represents the development direction of current welding machine power supply. Due to the commercialization of IGBT large-capacity modules, this power supply has a broader application prospect.
Most of the inverter welding machine power supply adopts the method of AC-DC-AC-DC (AC-DC-AC-DC) conversion. The 50Hz alternating current is converted into direct current by full-bridge rectification, and the PWM high-frequency conversion part composed of IGBT inverts the direct current into a high-frequency
(4) moduleThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;
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.
(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;
(6)module The design is relatively simple, without too many parts, just a power module and a few discrete components;
In many fields, switching 48V input power supply modules play a role that cannot be ignored and are very important.
