Development status of high-power inverters in the international market
Nowadays, major foreign inverter manufacturers have formed their own different series of products on the basis of their own brands, and their control systems have been completely digitalized. Almost all products have vector control function, and the perfection of craftsmanship is also a major feature of foreign brands. In developed countries, as long as there is a motor, there is a frequency converter. Its current development is mainly as follows:
①Technology development started early and has a considerable scale of industrialization.
②The frequency converter that can provide super power has exceeded 10000KW.
③ The technical standards of frequency conversion speed regulation products are relatively complete.
④ The related supporting industries and industries are already quite large.
⑤ Power devices that can be produced, such as IGBT, IGCT, SGCT, etc.
⑥ High-power frequency conversion products have been widely used in various industries, and achieved significant economic benefits.
⑦ Product internationalization and localization are deepened.
⑧New technologies and new processes emerge in an endless stream, which are widely and rapidly applied to products.
