What are the advantages of vehicle power supply module?(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) vehicle 48V input power supply module The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;
(2) Parallel connection of redundant hot backup. Connecting the output terminals of the same module through diodes in parallel can enhance the output capability and improve the reliability of the power supply system. In principle, if it cooperates with the corresponding output alarm circuit, put the module on the busbar that can be removed, so that the faulty module can be replaced in time. There is no limit to the number of modules connected in parallel in this way. D is generally a Schottky diode.
(3) Series expansion. Connecting the output terminals of the same module in series can double the output voltage and increase the power accordingly, and the series output terminals must be connected with diodes for protection.
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
(3) The technology is relatively simple, and it is easy to meet the relevant requirements;
(4) vehicle 48V input power supply moduleThe 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) vehicle 48V input power supply 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.
