Problems solved by technology

[0002] Traditional refrigerator compressors generally use the auxiliary coil to be directly connected in series with a PTC (thermistor) to start. After the refrigerator compressor is started, there is still a small amount of current flowing through the auxiliary coil. There is maintenance power consumption and zero power consumption cannot be achieved.
