Inverter is the application of frequency conversion technology and microelectronics technology, by changing the frequency of motor power supply to control the AC motor power control equipment. The inverter is mainly composed of rectification (AC to DC), filtering, inverter (DC to AC), brake unit, drive unit, and detection unit micro-processing unit. The inverter adjusts the voltage and frequency of the output power supply by breaking the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed control. In addition, the inverter has a lot of protection functions. , such as over-current, over-voltage, overload protection and so on. With the continuous improvement of industrial automation, inverters have also been widely used.
China's inverter market has maintained a growth rate of 12% to 15% in recent years. Industry insiders expect that the growth rate of the installed capacity (power) of the upconverter in the Chinese market is actually around 20%, and the potential market space is about 120 billion to 180 billion yuan. Last year was a crucial year for the Twelfth Five-Year Development Plan. The government work report placed high demands on energy saving and emission reduction in industry and the public sector. At the same time, the inverter industry has also ushered in an opportunity for development. In fact, during the 12th Five-Year Plan period, Chinaâ€™s environmental protection investment will reach 3.1 trillion yuan, and the total output value of energy-saving and environmental protection industries will reach 5.3 trillion yuan. As the main force and vanguard of energy-saving emission reduction, there is a huge future in the future. Market demand. At present, the concept of China's energy-saving society is being actively promoted, and the national government has accelerated the introduction of industrial policies to indicate the direction of energy-saving development.
