Abstract

The invention discloses a compressor start driving circuit, method and device and a computer storage medium, and belongs to the technical field of compressors. The compressor start driving circuit comprises a silicon controlled rectifier connected in parallel with an operation capacitor which is in serial connection with an auxiliary winding of a present compressor, and a digital pulse control circuit for generating a trigger signal of the silicon controlled rectifier; the two ends of the digital pulse control circuit are connected with the auxiliary winding and an AC input power supply respectively, and the digital pulse control circuit is used to determine a first trigger signal strategy that matches attribute information of the present compressor, and generates the first present triggersignal according to the trigger signal strategy so as to start the present compressor. Thus, the compressor is started by the digital control circuit, and the compressor is driven more accurately.

Description

technical field [0001] The present invention relates to the technical field of compressors, in particular to a compressor startup drive circuit, a drive method, a device and a computer-readable storage medium. Background technique [0002] Many smart home appliances include an important device, the compressor, such as refrigerators, air conditioners, etc. Fixed-frequency compressors still maintain a high proportion due to their large price advantages, such as: household refrigerators, freezers, etc. Due to their low power, the energy-saving effect of frequency conversion is not obvious, and products including fixed-frequency compressors occupy a significant share Market Advantage. [0003] At present, the start-up of low-power compressors is controlled by thyristors, and the trigger signals of thyristors are generally generated by analog drive circuits, that is, the drive of compressors can include: built using discrete components The analog circuit can control the conduct...
