Title:
OPERATION CONTROL METHOD AND SYSTEM, AND COMPRESSOR, AIR CONDITIONER AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/107956
Kind Code:
A1
Abstract:
Disclosed are an operation control method and system, and a compressor, an air conditioner and a readable storage medium. The operation control method comprises: collecting a power supply signal of a bus; determining a fundamental wave phase corresponding to the power supply signal, and determining a higher harmonic signal corresponding to the fundamental wave phase; and according to the higher harmonic signal, determining a duty ratio input into a power factor correction controller; or acquiring parameter information of an electrical load, and collecting a fundamental wave amplitude corresponding to a power supply signal; determining a compensation harmonic signal corresponding to the parameter information and the fundamental wave amplitude; and according to the compensation harmonic signal, determining a duty ratio input into a power factor correction controller. By means of applying the operation control method, the heating quantity of a bus capacitor can be effectively reduced, such that the reliability and service life of the bus capacitor can be improved when the bus capacitor is not replaced with a bus capacitor with a larger capacity and the hardware cost is not increased.
