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 power supply module 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;
(4) vehicle 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 power supply module The design is relatively simple, without too many parts, just a power module and a few discrete components;
(3) Before the installation is completed and the power is turned on, the wiring on each terminal should be checked and checked again to ensure that the input and output, AC and DC, single-phase and multi-phase, positive and negative, voltage and current values are correct. Prevent the occurrence of reverse and wrong connections.
(4) For high-power power supplies, there are generally two or more "+" output terminals and "-" output terminals. In fact, they belong to the same output electrode, but for the convenience of user wiring, they are connected together internally.
(5) The module power supply is not allowed to work at full load for a long time. The utilization rate of linear power supply should be controlled within 60%; the utilization rate of switching power supply should be controlled within 80%, otherwise it may cause early artificial failure of module power supply.
Drive module power supply
The frequency converter power supply is mainly used for the frequency conversion and speed regulation of the AC motor. The main circuit of the inverter power supply adopts the AC-DC-AC scheme. The power frequency power supply becomes a fixed DC voltage through a rectifier, and then a PWM high-frequency converter composed of high-power transistors or IGBTs inverts the DC voltage into an AC output with variable voltage and frequency. The output waveform of the power supply is similar to a sine wave. It is used to drive the AC asynchronous motor to realize stepless speed regulation.
In many fields, switching power supply modules play a role that cannot be ignored and are very important.
