[0002] With the popularization and application of frequency conversion compressors, various compressor manufacturers have developed frequency conversion compressors with different cooling capacity and COP. However, the motor parameters of frequency conversion compressors from different manufacturers are basically different. Compressor motor parameters are also different. At present, each inverter compressor needs to be equipped with a dedicated driver to maximize its efficiency. As a result, there are more and more types of inverter refrigerator driver boards.

Embodiment Construction
[0017] A method for universalizing the frequency conversion refrigerator drive board of the present invention is: use the drive board MCU to automatically determine and obtain the type of frequency conversion compressor used in the frequency conversion refrigerator by detecting the peripheral circuit, and when the frequency conversion compressor needs to be turned on, the energy to drive the frequency conversion compressor is invoked The driver of the machine to open and close the inverter compressor.
[0018] Such as figure 1 and figure 2 As shown, the connection methods between the peripheral circuit and the MCU of the driver board are divided into: the connection method of short-circuiting different positions through jumpers, the connection method of different positions through the toggle switch, and / or the replacement of the EEPROM memory with pre-stored driving parameters. connection method.
[0019] The driving parameters of different types of variable frequency compr...

The invention discloses a variable-frequency refrigerator driving plate universalization method. The method is characterized in that a driving plate MCU obtains the models of variable-frequency compressors adopted for a variable-frequency refrigerator by detecting a peripheral circuit, and therefore the variable-frequency compressors can be started and stopped by calling a driving program capable of driving the variable-frequency compressors. By means of the variable-frequency refrigerator driving plate universalization method, motors of the variable-frequency compressors of different models can be driven, and therefore driving plates of the variable-frequency compressors can be universalized.
Description
technical field [0001] The patent of the present invention relates to a generalization method of the frequency conversion refrigerator drive board. Background technique [0002] With the popularization and application of frequency conversion compressors, various compressor manufacturers have developed frequency conversion compressors with different cooling capacity and COP. However, the motor parameters of frequency conversion compressors from different manufacturers are basically different. Compressor motor parameters are also different. At present, each inverter compressor needs to be equipped with a dedicated driver to maximize its efficiency. Therefore, there are more and more types of inverter refrigerator driver boards. Refrigerator companies have gradually independently developed variable frequency compressor drive solutions. For refrigerator companies, they hope that the fewer types of drive boards the better, so as to facilitate material management and improve produ...
