Abstract

The invention discloses a compressor control method and device, a storage medium and a compressor. The method comprises the steps of obtaining the required frequency of the compressor; determining a PWM duty ratio and a bus voltage value of a PFC circuit in a control end of the compressor according to the required frequency of the compressor; and according to the PWM duty ratio of the PFC circuitand the bus voltage value, adjusting the operation frequency of the compressor, so that the operation frequency of the compressor reaches the required frequency of the compressor. According to the method, the problem that the operating frequency of the compressor cannot meet the required frequency when the required frequency of the compressor reaches the maximum value of the effective voltage of the compressor can be solved, and the effect that the operating frequency of the compressor can meet the required frequency is achieved.

Description

technical field [0001] The invention belongs to the technical field of compressors, in particular to a compressor control method, device, storage medium and compressor, and in particular to a compressor control method, device, storage medium and compressor based on a multi-channel interleaved PFC circuit . Background technique [0002] Generally, the control strategy of the compressor is to send the command frequency through the main control chip, and adjust the frequency of the compressor through the drive module, so that the frequency of the compressor reaches the frequency required by the main control; this control strategy is simple and effective, and the control logic Simple, but when the required frequency reaches the highest value of the effective voltage of the compressor, the effective voltage cannot be increased, so that the operating frequency of the compressor cannot meet the required frequency. [0003] The above content is only used to assist in understanding ...
