What are the advantages of high-voltage input module power supply?(2)

Internationally, the inverter power supply series products below 400kVA have come out. In the early 1980s, Toshiba Corporation of Japan was the first to apply AC variable frequency speed regulation technology to air conditioners. By 1997, its share had reached more than 70% of Japan's household air conditioners. Inverter air conditioners have the advantages of comfort and energy saving. In the early 1990s, domestic research on inverter air conditioners began. In 1996, the production line was introduced to produce inverter air conditioners, which gradually formed a hot spot for inverter air conditioner development and production. A climax is expected around 2000. In addition to the variable frequency power supply, the inverter air conditioner also requires a compressor motor suitable for variable frequency speed regulation. Optimizing the control strategy and selecting functional components are the further development direction of the inverter power supply for air conditioners.

(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) high-voltage input module 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) high-voltage input module power supplyThe development cycle is relatively short, there are many choices in input and output, and the changes are quite flexible;

Diode loss
Diode rectification is used in traditional rectification, and Schottky diode rectification is generally used under low voltage output conditions. Compared with other rectifier diodes, Schottky diodes have the advantages of faster switching speed and lower forward voltage, but Schottky diodes The forward voltage drop of the diode is related to the size of the rectified output current. The larger the rectified output current is, the greater the forward voltage drop, which may be as high as 0.5~0.6V or more, and the reverse leakage current of the Schottky diode is larger. .

(5) When the design of the product needs to be changed, it can be simply converted or connected in parallel;

(6) high-voltage input module power supply The design is relatively simple, without too many parts, just a power module and a few discrete components;

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