Abstract

The invention relates to the technical field of intelligent household appliances, and discloses a control method for a compressor. A control circuit of the compressor comprises a booster circuit. The method comprises the following steps: under the condition that an air conditioner shutdown instruction is received, obtaining the back electromotive force of the compressor and the bus voltage of the compressor; if the sum of the counter electromotive force of the compressor and the bus voltage of the compressor is larger than preset bus safety voltage, controlling the booster circuit to be disconnected, and obtaining new compressor bus voltage; and according to the new compressor bus voltage, determining the shutdown time of the compressor. According to the method, after the compressor bus voltage is controlled within a reasonable range through the booster circuit, the compressor is controlled to stop; and the problem of power supply overvoltage caused by sudden stop of the compressor is solved, and the service life of related components of the air conditioner is prolonged. The invention further discloses a control device for the compressor and an air conditioner.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a control method and control device for a compressor, and an air conditioner. Background technique [0002] At present, during the use of the air conditioner, the compressor stops running at high speed, and the compressor stops at high speed, causing the back EMF voltage of the compressor to be too high. After the back EMF voltage is superimposed on the bus voltage, the bus voltage suddenly rises, triggering Over-pressure protection makes the compressor shut down. Due to the short rise time of the bus voltage, the overvoltage protection caused by the above situation is usually not dealt with, but frequent overvoltage shocks will damage the life of air conditioning components. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] In related...
