The chip on the refrigerator inverter board regulates the compressor speed by controlling the driving voltage and current of the 6 IGBTs. These chips have high-speed computing and data storage functions, and can be finely controlled according to different needs, so as to achieve the purpose of accelerating and decelerating the compressor.
Six IGBTs are connected in series or parallel through connectors to control current flow and voltage changes in different directions.
In this way, the chip on the inverter board can achieve efficient energy conversion and precise compressor control, improving the performance and service life of the refrigerator.
