Title:
COMPRESSOR FLUX-WEAKENING CONTROL APPARATUS, AIR CONDITIONER, METHOD AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/107731
Kind Code:
A1
Abstract:
The present application relates to the field of compressor control, and disclosed therein is a compressor flux-weakening control apparatus, comprising: a main circuit unit and a compressor, the main circuit unit providing a power supply for the compressor; and further comprising: a compressor rotational speed acquisition unit and a control unit used for comparing compressor rotational speed ω to a compressor rotational speed threshold ω1, and performing the following control on the main circuit unit according to the comparison result: when the compressor rotational speed ω<ω1, controlling the output voltage of the main circuit unit to be a fixed value V0; when the compressor rotational speed ω≥ω1, temporarily not entering flux-weakening control, and increasing the output voltage of the main circuit unit; and when the voltage of the main circuit unit is unable to continue increasing, the compressor entering flux-weakening control. The foregoing manner delays to the greatest extent the time at which the compressor enters flux-weakening control, and ensures to the greatest extent that the compressor does not enter flux-weakening control, which thus improves system stability. Further disclosed in the present application is a compressor flux-weakening control method, a storage medium, and an air conditioner.
