Domestic high-voltage inverter market demand

High-voltage inverter market in China will usher in a period of rapid growth

The frequency converter is the power converter in the motion control system. Today's motion control system is a technical field containing a variety of disciplines. The general trend is: the exchange of drives, the high frequency of power converters, and the digitization, intelligence, and networking of control. Therefore, as the important power conversion component of the system, the frequency converter provides controllable high-performance variable-voltage variable-frequency AC power and has been rapidly developed.

Business does not stop

After about 30 years of R&D and application practice, with the development of new power electronic devices and high-performance microprocessors and control technologies, the performance and price ratio of frequency converters is getting higher and lower, and the volume is getting smaller and smaller. Continuous improvement in reliability has led to new efforts to further reduce the size, weight, performance, and functionality of inverters and reduce pollution. The merits and demerits of inverter performance depends on the effects of the harmonics of the output AC voltage on the motor, the harmonic pollution of the power grid and the input power factor, and the energy loss ( ie, efficiency ) of the inverter itself. Inverter is still making continuous progress. All manufacturers are pursuing excellence. This is also the precondition for promoting the development of the industry. As long as the company is always looking forward, the industry will naturally be better.

With the increasing demand for large-scale frequency conversion devices in China and the successful development of high-end frequency conversion products, the development of intelligent inverters has become an urgent task. Our basic performance of frequency conversion has not yet reached the appropriate level, and the market has not yet reached this level. Fortunately, we have seen some domestic inverter companies have carried out beneficial R&D practices. On the one hand, they have digested foreign advanced technologies and on the other hand tried to introduce their own frequency conversion standards. We look forward to major breakthroughs in the domestic inverter industry.
