What are the advantages of DC module power supply?(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)DC module 24V input power supply  The quality is relatively excellent, the quality is relatively stable and reliable, and it can be produced automatically;

Power active filter is a new type of power electronic device that can dynamically suppress harmonics. It can overcome the shortcomings of traditional LC filters and is a promising harmonic suppression method. The filter consists of a bridge switching power converter and a specific control circuit. The difference from the traditional switching power supply is: (1) not only feedback the output voltage, but also feedback the average input current; (2) the current loop reference signal is the product of the voltage loop error signal and the full-wave rectified voltage sampling signal.

(3) The technology is relatively simple, and it is easy to meet the relevant requirements;

Power Active Filter
When the traditional alternating current-direct current (AC-DC) converter is put into operation, a large amount of harmonic current will be injected into the power grid, which will cause harmonic loss and interference. For example, when uncontrollable rectification is added with capacitor filtering, the third harmonic content on the grid side can reach (70~80)%, and the power factor on the grid side is only 0.5~0.6.

(4) DC module 24V input 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)DC module 24V input power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

 In many fields, switching 24V input power supply modules play a role that cannot be ignored and are very important.
