Inverter Market Development Trend in China2016-11-09
Key words: frequency converter, market, development trend Frequency changer in many profession all has the use, the frequency changer technical content is more and more high to use the scope more and more widely, along with the electronic technology development, in recent years the frequency changer market year by year increases, the frequency changer performance can more and more High, the frequency changer development tendency is what kind of? The application of the inverter has 200 years of history, and now the inverter size tends to be small, how do we judge a converter performance? 1, depends on their energy loss (ie, efficiency) how much. 2, depends on its power grid harmonic pollution and input power factor. 3, to see it the output AC voltage harmonics on the motor impact. The development trend of the frequency changer is: Drive the communication, network and intelligence. Frequency converter as an important power system components, to provide controllable high-performance variable-voltage AC power supply and the rapid development. Inverter with voltage regulator, FM, voltage, speed and other basic functions, AC - DC - AC inverter is the development trend: 1, pulse width modulation transformer control method can use the sine wave pulse width modulation (SPWM) control, elimination of the specified number of harmonic PWM control, current tracking control, voltage space vector control (flux tracking control). 2, the main circuit power switching components from the off, modular, intelligent, continuous improvement of switching frequency, switching losses further reduced. Inverter is the overall direction of the development of more intelligent, inverter is used to save power, the installation of the inverter motor, according to conditions can save 15% -65%, if the enterprise power consumption is very large , The remaining power is very alarming. China is an industrial country, the use of frequency converter will be more and more places, inverter market potential in China is huge. However, the gap is very large inverter market, the inverter market will be getting better and better, more professional frequency converter will be born with the development of science and technology.
