Industrial Power
As one of the mainstream new power electronic devices, IGBT is widely used in rail transit, smart grid, aerospace, electric vehicles, new energy equipment, and industrial fields (AC/DC conversion and frequency conversion control in high-voltage and high-current occasions). It is the core technology in the above applications. According to relevant data, China's IGBT market has been monopolized by international giants, and 90% of the shares are in the hands of overseas giants such as Infineon and Mitsubishi.
Motor drive
Electric motors are widely used in industry worldwide. Drive the operation of pumps, fans and conveyor belts to drive lifting trucks and elevators; it is also widely used in the manufacture of compressed air or refrigeration. Given its widespread development, it is not surprising that electric drives account for 70% of industrial power consumption. If no energy saving measures are taken, the global power consumption of electric motors will double by 2030.
Power quality
Generally speaking, there are two kinds of power quality equipment using IGBT power devices: 1. Active power filter, full name: active power filter, English: Active power filter (APF for short), the function of APF is to suppress harmonics in the power grid; 2. Reactive power compensation, full name: static reactive power compensation generator, English: Static Var Generator (SVG for short). SVG's function is to compensate reactive power and improve power consumption efficiency.
