The development background of the high voltage inverter

Electronic technology and the rapid development of computer technology directly promoted the electric rotary technology revolution, with ac speed control instead of dc speed control, computer numerical control replace analog control has become a development trend.High voltage inverter, the silicon controlled rectifier, thyristor inverter, etc, and the advantages and disadvantages of many components, the harmonic of power grid, and motor have influence. In recent years, the development of some new device will change this situation, such as IGBT, IGCT, SGCT, etc.
high voltage inverter development

With China's further expand consumption growth, investment will continue to increase. In this way, a lot of industry factory and integrated power application will need to energy saving measures. Secondly, the Asian OEM, processes and heavy industry in the market power control for the acquisition opportunities is expected to lead to significant growth potential. High voltage frequency converter is many large automation engineering indisensable part. The converter help maximize assets and to manage energy consumption situation.

1, the domestic high voltage inverter technology standard remains to be standard.
2, high voltage frequency converter of supporting the industry is not developed.
3, production technology is backward, barely meet the technical requirements of the frequency converter product, but the price is low.
4, frequency converter is used in power semiconductor, drive circuit, electrolytic capacitors, and other key device completely rely on imports.
5, and the developed countries of the technology gap in narrow, with independent intellectual property rights of the products are applied in the national economy.
6, has been developed with instantaneous power down again, failure to restore the functions of frequency converter.
