What inverter is inverter

inverter does not mean a specific brand or type of inverter. It is the English name of the inverter.

The more famous brands are these: Delta DELTA, Yaskawa Yaskawa, Mitsubishi Mitsubishi, Emerson Emerson, SIEMENS Siemens, Schneider Schneider, Fuji Electric FujiElectric and so on. These are the ones that will be written in the relevant trademarks above the inverter.

Inverters convert direct current (DC) into alternating current (AC). The general composition is as follows:

1, rectifier unit: the operating frequency of a fixed AC power conversion into DC power.

2, high-capacity capacitors: storage of converted power.

3, inverter: by high-power switching transistor arrays composed of electronic switches, DC power into different frequency, width, amplitude of the square wave.

4, the controller: according to the set program work, control the amplitude and pulse width of the output square wave, so that the superposition of the AC power for the approximate sinusoidal wave, drive the AC motor.

Expanded Information:

. p>The background of the birth of frequency conversion technology is the widespread demand for stepless speed regulation of AC motors. The traditional DC speed control technology is limited in application due to its large size and high failure rate.

After the 1960s, power electronic devices commonly used thyristor and its upgraded products. But its speed performance is far from being able to meet the needs. 1968 Danfoss as the representative of high-tech enterprises began to mass production of inverters, opened a new era of industrialization of inverters.

Beginning in the 1970s, the research of pulse width modulation variable voltage variable frequency (PWM-VVVF) speed control has been a breakthrough, and the improvement of microprocessor technology after the 1980s has made various optimization algorithms easy to implement.

In the mid-to-late 1980s, the United States, Japan, Germany, Britain and other developed countries, VVVF frequency converter technology is practical, commodities into the market, has been widely used. The earliest inverter may be the Japanese bought the British patent developed. However, the United States and Germany with the advantages of electronic component production and electronic technology, high-end products quickly seize the market.

Step into the 21st century, the gradual rise of domestic inverter, has gradually seized the high-end market. Shanghai and Shenzhen has become the forefront of the development of domestic inverters, emerging as a number of well-known domestic inverters, such as Huichuan inverter, Invertron inverter, Anbangxin inverter, Ou Rui inverter. Among them, Anbangxin inverter was founded in 1998, is one of the earliest manufacturers of inverters in China. Over the past ten years, Anbangxin people with rich cultural heritage as the cornerstone, supporting the growth of enterprises earlier through the TUV agency ISO9000 quality system certification, was awarded the "national high-tech enterprises", for many years was named "China's top ten domestic brands of inverter user satisfaction

The company was awarded "National High-tech Enterprise" and "China's top ten domestic brands of inverter user satisfaction" for many years.
