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;
HVDC module power supply
High-power switching high-voltage DC power supplies are widely used in large-scale equipment such as electrostatic dust removal, water quality improvement, medical X-ray machines and CT machines. The voltage is as high as 50~159kV, the current reaches more than 0.5A, and the power can reach 100kW.
Since the 1970s, some Japanese companies have begun to use inverter technology to rectify the mains and invert it to an intermediate frequency of about 3kHz, and then boost it. In the 1980s, high-frequency switching power supply technology developed rapidly. Siemens of Germany uses power transistors as the main switching elements to increase the switching frequency of the power supply to above 20kHz. And the dry-type transformer technology is successfully applied to the high-frequency high-voltage power supply, the high-voltage transformer oil tank is cancelled, and the volume of the transformer system is further reduced.
(2)DC module Marine boost voltage 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;
(4) DC module Marine boost voltage power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;
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.
(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;
(6)DC module Marine boost voltage 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 voltage power supply modules play a role that cannot be ignored and are very important.
