Inverter refrigerators, air conditioners, washing machines, etc. are all driven by one-way AC motors such as compressors, and are equipped with inverter modules to realize variable speed control of the motor to control the cooling capacity or the speed of the washing machine. Compared with the traditional fixed-frequency working mode, frequency conversion is more energy-saving and has lower noise. It is accepted and favored by more and more consumers, and frequency conversion is becoming the mainstream of industry development.
Our company uses the trench field stop IGBT technology (Trench Field Stop) theory, adopts high-density device structure design and advanced ultra-thin chip processing technology, optimizes the carrier injection efficiency and carrier distribution, and significantly reduces the device. Saturation voltage drop and turn-off loss, thereby reducing device power consumption and improving system efficiency, it has a good application in the field of servo drives.
